Leaning Addition and Subtraction Regrouping this Month
|
 |
It can be difficult for children to understand the abstract concept of regrouping, so many lessons on addition with regrouping use manipulatives to teach it in a concrete way. Manipulatives are any physical objects that students can use to represent addition. You can also use everyday objects, like dried beans or pasta as manipulatives.
Draw two columns on a large sheet of construction paper. Label the left column '10s' and the right column '1s.'
Set up your manipulatives by placing 10 dried beans into mini paper cups. Each paper cup represents 10.
Set up your math problem on the construction paper. If you want to represent 22, use two cups and two beans. If you want to represent 19, use one cup and nine beans.
Children can solve the problem by counting 10 beans from the '1s' column and placing them in a cup. Those beans go into the '10s' column. Now there are four cups and one bean, so the answer is 41.
