I like an active classroom where everyone is busy. If you stop in one day it will look like chaos, but it is a carefully orchestrated chaos that cleverly disguises all the learning that we are doing. I use a lot of activities -- and keep the kids moving. Research says that if anyone sits for more than 15 minutes, their brain disengages and learning is not happening. So I design a lot of activities to get kids moving, talking, thinking and participating.

Pythagorean Theorem Digital Matching Cards

(0)
Students practice using the Pythagorean Theorem in this quick and easy Drag and Drop activity in Google Slides for Google Drive or Microsoft One Drive. Students have 16 diagrams of right triangles with a missing side and must find the answer on one of the other slides. Students then cut the slide from its position and paste it next to the problem. The first time I used digital matching cards in the classroom, students took 2 days to complete all 16 pairs of cards, subsequent times they were much faster to understand the process. Included in the directions is the link to the activity in Google Slides, answer key, instructions on how to share with students and instructions on adding additional notes or instructions to students before sharing.

Domain and Range of Quadratics Digital Activity

(0)
Students practice finding the Domain and Range of Quadratics in this quick and easy Drag and Drop activity in Google Slides for Google Drive or Microsoft One Drive. Students look at each graph and determine which of the pieces correctly identify the Domain and Range and either move the piece to the appropriate place with a mouse, cut and paste in position or use a touchscreen to drag. On the accompanying Google Sheets (if you choose to use the link) Students can type in the letter of the range for each numbered equation and check if they are correct. I give my students the link to check when they have finished placing all the pieces. If their answer is correct, the space on the sheet will change color. If the answer is wrong, no change. Links to both are included as well as an answer key and detailed instructions on how to upload and share with students.
Corner Collaboration--Evaluating Functions

Corner Collaboration--Evaluating Functions

(0)
Corner Collaboration is a Kagan strategy also called 4 Corners where students work in their home group to solve problems and then at teacher signal, go to pre determined corners to compare answers with a new group and get a different perspective on solving problems. In this activity, students will evaluate the given function with the given value. There are 7 problems on each sheet. Each group will get a different version of the worksheet as identified by a musical symbol. I allow about 15-20 minutes for the students to complete (your class may need more) and then when the timer goes off, students go to the corner with the symbol matching their sheet. They can compare answers and discuss any errors. When the timer goes off again, we meet as a group to discuss any difficult or confusing problems, and this gives me an idea to reteach or move on. Great for promoting discourse in the classroom.

There are 4 different worksheets with 6 problems each. Each group will get a different version of the worksheet as identified by a musical symbol. I allow about 15-20 minutes for the students to complete (your class may need more) and then when the timer goes off, students go to the corner with the symbol matching their sheet.

Partner Practice Order of Operations

(0)
Great collaborative resource to have students practice the order of operations. Students can work in pairs (trios will work as well), one person completes A and the second person completes B and then compares answers. Problems are different, but answers are the same. Self - checking--when students have the same answer they know they are correct, but different answers mean they need to go back and check for their mistake. When students are stumped, one person visits another pair, gets help and is responsible for sharing the solution and all the steps with the partner. Encourages discource in the classroom as they practice this important skill.
