• Product Description
• StandardsNEW

Estimating sums and differences is often a hard concept for students to understand. These math task cards can help them review the concepts in a way that is fun and provides them with plenty of practice.

What is Included?

• Two sets of task cards - 32 addition cards, and 32 subtraction cards
• Each set works progressively, beginning with simply rounding a three-digit number, and then asks students to round two numbers and then add (or subtract) them together, and finally, students estimate the sum (or difference) and then find the exact answer. Four task cards also ask students to see if an estimate is reasonable.
• All numbers are rounded to the nearest hundred and are three-digit numbers.

Take a look at the preview file to see more of what is included in these task cards.

Thanks,

Angie Campanello
