# Similar Triangles & Indirect Measurement Scavenger Hunt – 7th-8th – PRINTABLE

\$3.00

Categories: ,

## Description

Do your students understand how to use similar triangles to solve indirect measurement problems? Could they use more practice finding the missing side using similar triangles? This class activity is FUN and gets kids up and moving!

Use this as extra practice with kids in 7th or 8th grade to help them see the proportional relationships in similar triangles and apply their knowledge to real world problems.

This scavenger hunt includes a variety of problems to practice working with similar triangles. Four problems show similar triangles and require students to find the missing side length. Six problems are word problems which students can solve using indirect measurement (with similar triangles).

In addition, a recording page is included so students can show their work for each problem as they make their way around the room.

### How the Scavenger Hunt Works:

The scavenger hunt includes 10 problems for students to solve. To set it up, post all 10 problems in various locations around your room. Give each student a recording sheet and then you’re ready to get started!

To begin, kids can start with ANY of the problems. They solve it on their recording sheet and then have to FIND the solution somewhere around the classroom.

When they find the answer to the problem, they solve the NEXT problem in the scavenger hunt.

Eventually, they will end up back where they started and they’ll know they have completed the hunt correctly.

### Math Skills Covered in the Similar Triangles Scavenger Hunt:

• Creating proportions with similar triangles
• Find the missing side length of a triangle
• Matching pairs of similar triangles (on the practice worksheet)
• Solving indirect measurement word problems by creating similar triangles

### Tips for Using This Scavenger Hunt in the Classroom:

• Give kids a clipboard to make it easier to record their work and answers as they move about the room
• Let kids work with partners as they make their way through the scavenger hunt
• If you have a large class, assign kids a starting problem so they’re not all bunched together at the same location
• Collect the recording sheets as an informal assessment of how your students are doing
• Use this as an end-of-unit review, end-of-the-year review or as a substitute activity (be sure to do this with your students prior to leaving it with a sub so students know how it works)

Use these with students who need additional support and practice, as an individual grade after the whole class activity, or to send home as homework practice.

There are two worksheets included.

On the first practice page, students match pairs of similar triangles. Students will look at the side lengths to find triangles with proportional side lengths. Once they find the matches, they can then solve the silly riddle.

On the second page, students practice solving word problems with indirect measurement. There are two word problems, with room for students to draw a picture, show their thinking and solution, and then explain what their solution means in the context of the problem.

• Setup and Teaching Tips
• 10 Scavenger Hunt Problem Cards (half pages)
• Scavenger Hunt Recording Page
• Two Independent Practice Worksheets
• Answer Keys for the Scavenger Hunt and Worksheets
