Skills practiced
First graders learn that a two-digit number is made of tens and ones: 58 is 5 tens and 8 ones, not just a 5 and an 8 sitting next to each other. This page practices that idea in four ways. Your child splits numbers into tens and ones in a table, builds numbers from tens and ones, chooses the number that matches a description, and solves a final puzzle. Place value is the foundation for adding and subtracting two-digit numbers, so it is worth getting solid now.
Common Core 1.NBT.B.2: Reading a 2-digit number as groups of ten plus leftover singles
Your child reads the instruction out loud and explains in their own words what to do.
Work through the tasks in order: the first ones are easier and warm up for the next.
The task with a star is optional, for early finishers.
Check together with the answer key and redo only what was wrong.
Tips for parents and teachers
Bundle real objects to make tens: craft sticks with rubber bands, or 10 cereal pieces in a small cup. When your child says 47, have them show 4 bundles and 7 loose ones. The classic mix-up is writing 74 for 4 tens and 7 ones, or 502 for 5 tens and 2 ones; ask your child to read the number aloud and check the place of each digit.
Make it easier or harder
Easier: Work only with numbers up to 50 and keep bundles of ten on the table. Let your child build each number before filling in the table.
Harder: Ask for the number that is 10 more and 10 less than each number in the table, or have your child describe 100 in tens and ones.
