<ul><li>Teacher slideshow</li><li>Blank coordinate grid sheet</li><li>Online Practice</li></ul>

<h3>Importance of the Pythagorean Theorem</h3>Give students an opportunity to work on the problems together, and review the theorem and its importance before moving on. For today’s lesson, it may be easiest to provide students with a&nbsp;<a href="https://docs.google.com/document/d/1d_d9uVZxeuxsT33ZAqDUFizLI_VGmcDM5DnQVxkJEL4/edit">blank coordinate grid sheet</a>.<figure class="image"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_1f7f1b1ffe.png"></figure><h3>Activating prior knowledge</h3>Ask students to consider what they already know that could help them find the&nbsp;distance between the two points. Students can plot these points on their own graphs on their&nbsp;<a href="https://docs.google.com/document/d/1d_d9uVZxeuxsT33ZAqDUFizLI_VGmcDM5DnQVxkJEL4/edit">blank coordinate grid sheet</a>. If students are not sure where to start, ask them to draw a line to represent the distance. To help struggling students, you may need to draw the rest of the right triangle. Once students recognize that the distance represents the hypotenuse of the right triangle, they should recognize that the Pythagorean Theorem can help them find the missing side length of a triangle, which would represent the&nbsp;distance between the two points.<h3>Using the Pythagorean Theorem</h3>Once students draw the legs of the right triangle, ask them what the lengths of each leg would be. It’s helpful to write in the measurements of the legs so students can associate them with the right triangle on the graph. Then, as a class, solve `3^2 + 4^2 =&nbsp;c^2` to find that `c`, or the distance between the two points, is `5` units.<h3>Encourage collaboration</h3><figure class="image"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_d12ccea558.png"></figure>With the next example, give students a moment to plot the two points on their graphs on the&nbsp;<a href="https://docs.google.com/document/d/1d_d9uVZxeuxsT33ZAqDUFizLI_VGmcDM5DnQVxkJEL4/edit">blank coordinate grid sheet</a>. To support student discussions, give students a couple of minutes to attempt this problem with a partner or table group. Students should be able to explain how they found the lengths for each leg of the right triangle and then how they solved using the pythagorean theorem.<h3>Differentiation</h3><ul><li>Struggling students: It may be beneficial to use different colors so that it is easier for them to see the difference between the sides of the triangles they will need to draw.</li><li>Advanced students: Consider asking them how they would approach the problem if they did not have a coordinate grid given to them.</li></ul><h3>Example without a grid</h3><figure class="image"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_c7b77f127d.png"></figure>For this example, students will likely have to plot the points on their&nbsp;<a href="https://docs.google.com/document/d/1d_d9uVZxeuxsT33ZAqDUFizLI_VGmcDM5DnQVxkJEL4/edit">blank coordinate grid sheet</a> or create their own open coordinate grid with only the `x`- and `y`-axis. Students’ misconceptions related to coordinate grids may appear, like plotting the ordered pairs as `(y, x)` instead of `(x, y)`. Depending on students’ readiness, check that they plotted the points in the right areas. This can help prevent students from miscalculating with the wrong values. Another option is to have students check the leg lengths they find before giving you an answer.<h3>Class Activity</h3><figure class="image"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_a26f47430c.png"></figure>Depending on the amount of time left in class, you may be able to do multiple rounds of this activity. Students should use their&nbsp;<a href="https://docs.google.com/document/d/1d_d9uVZxeuxsT33ZAqDUFizLI_VGmcDM5DnQVxkJEL4/edit">blank coordinate grid sheet</a>. Let students know that they can use a new graph for each problem they do.&nbsp;On the first blank grid, students should pick `2` points to find the distance between. Then, they will calculate the distance. Students will then find a partner. Each partner will plot the points the other chose and find the distance. Partners should then check to see if their distances between the points they chose matched. If student answers do not match, encourage students to look through their work to figure out where the error may have been.

<h3>Warm-up</h3>Students should review the Pythagorean Theorem before applying it to a coordinate grid.

After you’ve completed the examples with the whole class, it’s time for some independent practice! ByteLearn gives you access to tons of practice problems for finding the&nbsp;distance between two points. Check out their online practice and assign to your students for classwork and/or homework!

In this lesson, students will learn how to find the&nbsp;distance between two points. Students will review the Pythagorean Theorem. Then, through student discussion and problem solving, students will learn how the Pythagorean Theorem can help them find the&nbsp;distance between two points. You can expect this lesson with additional practice to take one `45`-minute class period.

Distance Between Two Points Lesson Plan

Students will be able to&nbsp;find the missing angle measure of a triangle.

<ul><li>Teacher slideshow</li><li>Online Practice</li></ul>

Students should ideally recognize the right angle and recall that triangle angles add up to `180`. Allow students to explain their reasoning when reviewing. It may also help to remind students that it is okay to be incorrect, but they should at least try and come up with something that could help them solve the problem.&nbsp;<h3>Finding a missing angle measure in a triangle</h3>Give one more problem where they find the missing angle in a triangle. Since you’ve already discussed how the sum of the angle measure is `180^\circ`, students should be able to reason that `x = 93`.<figure class="image"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_6dd86a6746.png"></figure><h3>Basic algebraic example&nbsp;</h3>With the next example, students should be more familiar with what information they will need to focus on to&nbsp;find the missing angle measure of the triangle. Allow students some time to try to solve the problem, and encourage them to work with a partner to check their work.<figure class="image"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_8671f716f7.png"></figure>Students may be confused because of the algebraic expression. Remind students that the angles will still have a sum of `180`. Although some students may write an equation to find&nbsp;`y` directly `(y + 6 + 97 + 42 = 180)`, it is more likely that students will break it into separate parts:<h3>To find the measure of the missing angle</h3><ul><li>Adds `97` and `42`. Then subtracts from `180`.&nbsp;</li><li>Subtracts each known angle individually (example: `180-97 = 83, 83-42 = 41`)</li></ul><h3>To find the value of&nbsp;`y`</h3><ul><li>Sets up an equation, like&nbsp;`y + 6 = 41`</li><li>Recognizes the whole angle is `41`, so they need to subtract `41-6` to find&nbsp;`y`.&nbsp;</li></ul><h3>Finding missing angles with combining like terms</h3>With the next example, give students an opportunity to try the problem on their own and check it with a partner. Some students may not immediately recognize the right angle, so it will be beneficial for you to walk around and listen to students’ conversations regarding the information given. Remind students of the warm up if needed!<figure class="image"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_603f6b4550.png"></figure>Through student or class discussions, students should be able to explain what the sum of the measures of the two algebraic angles are. Students should be able to solve for&nbsp;`z` using their reasoning skills; however, students may not immediately write an equation. If students are stuck, ask them how they can represent the sum of the two angles in two different ways to help guide them to `4z + 6z = 90` if needed.&nbsp;<h3>Missing angles activity</h3>To help students practice&nbsp;finding the missing angle measure of a triangle when there is not an image, have students recreate this table on a notecard or piece of paper. Explain to students that they will be creating their own triangles by coming up with angle measures. Encourage them to think about what the key idea behind this is. Students should be talking about how the sum of the `3` angle measures needs to be `180` degrees!&nbsp;<figure class="image"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_67a041f9cd.png"></figure>Have students work together to find the value of the variable for each row. Once students have their values, they can plug them back in to check their work!

<h3>Warm-Up</h3>With this first example, give students the opportunity to think about what they already know that could help them&nbsp;find the missing angle measure of the triangle. Allow students individual time to process the information and then have them share their thoughts to help support student discussions.

After you’ve completed the examples with the whole class, it’s time for some independent practice! ByteLearn gives you access to tons of practice problems for&nbsp;finding the missing angle measure of a triangle. Check out the online practice and assign to your students for classwork and/or homework!

In this lesson, students will learn how to&nbsp;find the missing angle measure of a triangle. Students will review angle relationships they already know. Then, students will work together to determine the relationships between the angles of a triangle to help them find the missing angle. You can expect this lesson with additional practice to take one `45`-minute class period.

Find Missing Angle Measure in a Triangle Lesson Plan - 8th Grade Math

Students will be able to apply the pythagorean theorem to real-world scenarios to find the missing side length in a right triangle.

<ul><li>Teacher slideshow</li><li>Partner Activity</li><li>Online practice</li></ul>

Give students a few minutes to answer the problems on their own before checking their answers with a partner. This warm up helps students review both finding a missing hypotenuse and finding a missing leg length. When students are finished, you can ask for volunteers to solve each problem on the board, explaining to the class as they go.<h3>Introducing Pythagorean Theorem Word Problems</h3>I find that the biggest struggle my students face when transitioning onto word problems is visualizing what the problem is and what it is asking for. So here’s what I do for the Pythagorean Theorem. I have students pair up. Depending on your specific group of students you may have them choose their own partners or you may assign partners. I give each student a copy of the&nbsp;<a href="https://drive.google.com/file/d/1SvNgWYsH8XzGAkhPIyGbnGpjKzQRLkKy/view?usp=sharing">partner activity</a>.<figure class="image"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_d9a9495908.png"></figure>I tell students to read the scenario, then work together to answer the questions! And I don’t give much more instruction than that! I am always impressed with the way students are able to work together to decode the problem and draw a picture of what it would look like.<h3>Discussion</h3>When it seems like students are finished, have a group come to the front of the room to share how they were able to solve the problem. If any groups drew their picture other ways, allow them to come up and explain too. It is interesting to see the similarities and differences between the way each student draws their picture, but how they are able to answer the same question. Below are some examples of types of drawings you may see.<figure class="image image_resized" style="width:50%;"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_a3acec7526.png"></figure>There is an answer key included in the&nbsp;<a href="https://drive.google.com/file/d/1SvNgWYsH8XzGAkhPIyGbnGpjKzQRLkKy/view?usp=sharing">partner activity</a> that can help as you go over the answers to questions with the class.

<h3>Warm up review</h3>Students already know how to solve numerical problems using the pythagorean theorem so start them with the warm up on slide `1`.&nbsp;

Now it’s time for students to practice on their own! Try doing a “Live” practice where students will all start the ByteLearn assignment at the same time. Hand out whiteboards or scratch paper and encourage students to draw pictures! Students will work on the same problems, in the same order, so it will be easy for you to see who you might be struggling and need more support.&nbsp;

At this point, students have already learned about the pythagorean theorem and how to find missing side lengths in a right triangle. In this lesson, we’ll introduce different real-world scenarios and how to solve those problems using the pythagorean theorem. You can expect this lesson to take one `45`-minute class period.

<ul><li>Teacher slideshow</li><li>Can you make a right triangle? Activity</li><li>Scissors&nbsp;</li><li>Online Practice</li></ul>

<h3>Review of the Pythagorean Theorem</h3>Remind students of the Pythagorean theorem. It’s helpful as you’re explaining the formula to use the phrasing, “A triangle is a right triangle IF the sum of the squares of the two smaller side lengths is equal to the square of the longest side length”. Be sure to point out the parts of the equation you’re referring to as you explain it this way. This helps students start considering the concept of the converse of the Pythagorean Theorem without explicitly bringing up that vocabulary.&nbsp;<figure class="image"><img src="https://bl-cms-bkt.s3.amazonaws.com/prod/image_119f27bab1.png"></figure><h3>Can you make a right triangle? Activity</h3>For this activity, students can work with a partner.

For 8 graders, find the area and perimeter of a right triangle worksheet can be very helpful in understanding the concept of area and perimeter which can help them to use the concept in real-life situations.&nbsp;&nbsp;The first step in finding the perimeter of a right triangle is to add up the lengths of all three sides. The formula for the perimeter of any triangle is P = a + b + c, where a, b, and c are the lengths of the three sides. In the case of a right triangle, one of the sides is the hypotenuse, which is the longest side and is opposite to the right angle.&nbsp;&nbsp;The other two sides are called the legs. To find the area of a right triangle, you need to use the formula A = 1/2 bh, where b is the base and h is the height. In the case of a right triangle, one of the legs is the base, and the other leg is the height. Therefore, the area of a right triangle is A = 1/2 (leg1 x leg2).
