PRODUCT DESCRIPTION

I created this activity to add to my unit on 2-digit addition and subtraction. They needed more practice with estimation. For this activity, students read real-world examples and round the numbers to get an estimate. For example 42 t-shirts and 17 t-shirts = ? about 50 or 60? Students show their work and circle the best estimate. 10 questions that can be used for practice/seatwork, a tool for small group instruction, homework, morning work, or even as an assessment. Check out all of my other math activities, including lots of practice with adding and subtracting 2-digit numbers!
