My students love these interactive math puzzles, and so do I! This set address expanded form for numbers 801 - 900.
Students will watch the board or screen, find the sum, and record their answer by shading in the correct square on their 900 chart. The slides in this set change automatically every 15 seconds.
You could use this activity as a whole group or make it a math center. This is also an engaging activity to give students while you are working on one-on-one assessments with other students. I have had my students complete this activity whole group with my LED projector and I they have also used our class desktop computers.
At the end of the game the "mystery picture" is revealed! The mystery picture in this set is a sailboat!
The 900 chart needed to play this game is included with two different printing options.
Please download the preview to see a sampling of the slides in this set.
