• Practice rounding individual numbers
• Determine compatible numbers for a set of given numbers

• Answer word problems involving estimation

These teacher-created worksheets can be used as independent practice pages after a lesson, a homework assignment or even a task to complete in a math center.

Teach How to Estimate the Sum and Difference of Two Numbers

We know that estimation is an important life skill as mental math is used in a variety of situations. Teaching your students from early on how to estimate sums and differences will give them the practice they need, so they are able to accurately estimate.

For students who may need additional support, start by assigning the 1-star worksheet. Additionally, consider providing number lines, base ten blocks, or completed examples to assist.

If there are students in need of a challenge, assign the 3-star worksheet or invite students to complete multiple levels of the task.
