Place Value to 100
Course overview
This course teaches Grade 1 students how two-digit numbers work. Students build numbers with tens and ones, read and write numbers to 100, and compare numbers using place value.
What students will learn
- Group ten ones as one ten.
- Read two-digit numbers as tens and ones.
- Write numbers to 100 with correct digits.
- Compare two-digit numbers by looking at tens first.
- Explain number choices using place value words.
Lessons
- Build Groups of Ten and Ones - Learn why ten ones can be counted as one ten.
- Read and Write Two-Digit Numbers - Connect digits, number words, tens, and ones.
- Compare Numbers to 100 - Decide which number is greater by comparing tens and ones.
Parent guide
Pace this course over three short sessions or one week of practice. Use small household objects so the child can build numbers before writing them. Ask the child to explain every answer using the words tens and ones. If a lesson feels hard, return to drawing quick tens as sticks and ones as dots.
Completion
A student finishes this course when they can build a two-digit number with tens and ones, read it aloud, write it correctly, and compare it with another two-digit number using a place value explanation.
