A set of 10 fun brainteasers for your students in lower grades.
Give your students one brainteaser a day or a week to try and solve. You could have a ‘solutions box’ at the front of the classroom. Each time your students are ready to submit their answer, they can write their name and answer on a piece of paper and drop it into the box. At the end of the day or week you would reveal the answer.
Or put them in your math centers as a problem solving activity.
