Mrs. Boubin's 3rd Graders Work on Math Skills

Modeling and adding 3-digit numbers with base ten blocks has been our objective this week in math. In Mrs. Boubin’s third grade classroom, students have been using these manipulatives to show regrouping in the tens and hundreds places. This has been a great visual to see how 12 ones cubes regrouped into 1 tens rod and 2 ones cubes. With the help of a partner, students each model a 3-digit number and then regroup to combine their blocks to show the sum. This activity and talking with a partner about math is a great way to learn the reason behind the phrase, “carry the one!”
