Number Detectives is a number recognition activity that can be used for whole groups or small groups. It can also be used in an interactive notebook, for early finishers and for intervention groups. The possibilities are endless! Students find the number indicated in the magnifying glass and cover it with crayons, markers, bingo dotters or laminate and use playdough or dry erase markers. Some numbers have a hidden number or design. Great way to reinforce and practice number recognition! Happy Hunting!
