My students asked for more of these brain teasers, so I created more. This 2nd card set has 14 different problems to solve using critical thinking skills. Students will figure out what the value of each shape is by working through the problems. Fun and exciting way to teach kids to problem solve and think! This is the 2nd set of cards I have made, and this set is a little more challenging than Set 1. Problems include both addition and subtraction. Created with color, but can also be copied in black and white. Great to use in small group or independent work in a center, station, or even partner work or seat work. Worksheet included for recording answers. Answer Key also attached so grading is easy.
