Estimation Fascination (division version) is a great math center activity that will help students with the tricky skill of estimating. This is a very important skill before students start using the standard division algorithm because it will allow them to check their answers for reasonableness. Additionally, estimating with division can be difficult because students cannot just round, they must find compatible numbers.
In this center activity, students will build a number using the included number cards. Students will then change their numbers to nearby numbers that are compatible so that they can use mental math to make an estimation of the quotient of the two numbers they originally drew.
This activity is quick and easy to put together for a fun and helpful math center. This center is nice because it helps practice multiple skills beyond estimating like changing expanded form to standard form (when drawing the number cards), finding compatible numbers, and practicing mental math.
