Representing and Adding 2/3-digit numbers using Base 10 Blocks (printable and digital centers)

Representing numbers using base ten blocks allows students to gain a concrete understanding of place value and regrouping. Even though, Base 10 blocks are not the only way to learn place value, and students should explore other manipulatives as well, however, they do offer a great way to represent numbers.

We have created some printable and digital activity cards based on Base 10 Blocks to help practice representing and adding 2/3-digit numbers using base 10 blocks. The printable cards can be used along with the physical base ten blocks or by themselves and the digital ones come with digital base 10 blocks that the students can drag and drop to solve the problems.

There are 4 levels of activities in this package

Level 1 and 2 : Represent numbers with 2 and 3 digits with and without the regrouping of 1s and 10s

Level 3 and 4 : Add 2 and 3 digit numbers with and without numbers the regrouping of 1s and 10s

How to use the cards

The students can use the printable cards to practice representing numbers after having some experience with the physical manipulatives. If the cards are laminated the students can draw the new tens and hundreds that form to better visualize the problem. With the digital cards, they can drag the base 10 blocks to regroup and reach to the answer.

Use the cards for individual practice, pair work, homework, or assessment.

We hope that you find this resource useful.
