How to Regroup Ones and Tens Using Base Ten Blocks
FAQs on Regrouping with Base Ten Blocks: Place Value Practice for Grade 1
1. What is regrouping in math for Grade 1?
Regrouping in math for Grade 1 is the process of changing groups of ones into tens, a key place value concept. For example, students learn to bundle 10 single units (ones) to form 1 ten rod, which is the foundation for understanding two-digit numbers and addition.
2. What is an example of regrouping ones using base ten blocks?
A simple example of regrouping ones is when you have more than 9 single blocks in the ones place. For instance, if you have 14 single blocks, you can:
- Group 10 of those single blocks together.
- Trade or regroup them for 1 ten rod.
- You are then left with 1 ten rod and 4 single blocks, which correctly represents the number 14.
3. How does regrouping help in addition for first graders?
Regrouping makes adding two-digit numbers easier and is a foundational skill for addition with carrying. When the sum in the ones column is 10 or more, first graders use regrouping to 'carry over' the new ten to the tens column, ensuring they find the correct total in their sums.
4. What is the method of regrouping tens and ones?
The method of regrouping involves counting the units in the ones place and bundling them into groups of ten. The basic steps are:
- Count the total number of single blocks (ones).
- If you have 10 or more, circle a group of 10 ones.
- Exchange that group for 1 ten rod.
- Write down the new total of tens and the remaining ones to form the two-digit number.
