2 Digit Addition

Here is a warm up to play with the number cards in the Math Kit. It's for 2 digit addition (without regrouping).

Use:

• multiple 11, 12, 13, 14 and 15 cards (print several sets)
• place value blocks

To play:

• shuffle all the cards and have them face down in a pile
• flip 2 cards
• build each number separately with blocks - e.g. for 11 make a ten and one
• combine the blocks to find the total, moving the tens together and the ones together

Extend this warm up idea into a full lesson activity by having your students draw, write or record each addition in their math book or on a whiteboard. 

Using blocks to model addition is a fun and effective way to introduce and reinforce the place value concepts within 2 digit addition. By engaging in hands-on activities, children can develop a strong foundation for understanding addition and develop a positive attitude towards mathematics.
