These cards are so versatile. They are great as a class-wide circle time activity on the SMARTboard, at stations, or nice to be used as enrichment or remediation in a one to one classroom. Can be used on any device. My students are really enjoying using the boom cards. These logic puzzles offer students a fun and challenging way to problem solve. The boom deck includes 20 different puzzles ranging in difficulty. Primary grade focus is 1st and 2nd. Great for math class, enrichment activities,
