2nd grade math: what your child learns, and how to help
2nd grade math is mostly about place value to 1,000 and adding and subtracting with regrouping. Here is what that means, where children often get stuck, and simple ways to help at home.
What your child learns in 2nd grade
Place value to 1,000
Know that 352 is 3 hundreds, 5 tens and 2 ones. Skip-count by 5s, 10s and 100s. Compare three-digit numbers.
Adding and subtracting within 100
Add and subtract fluently within 100, and within 1,000 using place value, including regrouping.
Fact fluency
Add and subtract within 20 from memory by the end of the year.
Money, time and measuring
Solve problems with dollars and coins, tell time to five minutes, and measure in inches, feet, centimeters and meters.
Foundations of multiplication
Odd and even numbers, and arrays: rows and columns of objects added up.
Based on the Common Core State Standards for Mathematics. Your state or school may order topics differently.
Where children often get stuck
- Subtracting the smaller digit from the bigger one in each column (52 − 17 = 45)
- Regrouping across a zero (300 − 128)
- Counting coins of mixed values
How to help at home
- Make change with real coins.
- Ask your child to explain a regrouping step out loud.
- Estimate first: "Will the answer be more or less than 50?"
How Kidscient helps with 2nd grade math
- It starts from your child's level, not their grade. A short, friendly check finds what your child can already do. Many children are ahead in some topics and behind in others.
- Homework help without answers. Your child snaps tonight's math homework and Curio helps with each problem by asking and hinting. Your child writes every answer. Code checks the arithmetic.
- Guided lessons on a whiteboard. Curio explains each step out loud while drawing it, then asks your child to try. Lessons open level by level; at the founding beta they start around the grade 4 level.
- Voice-first. Your child talks through their thinking, which is where the learning happens.
