Complete the number line to 10

Complete the number line to 10: a free Kindergarten math game for ages 5-6. Each round draws 5 questions; instructions are read aloud and every answer is checked and explained.

How it plays and why it helps

Children who can recite to ten often lose their place once the numbers are written and some are missing. Complete the number line to 10 is a Kindergarten game about that gap between saying and writing. A number line starts at 1 and ends at 7, 8 or 9, with four to eight empty boxes. Your child types the missing numbers, then says the whole line, as the instruction asks. It is the same five cards every round. Each answer is checked, and the explanation reads the full line back.

A number line is the counting sequence laid out in space. Each box holds the number after the one before it, which is exactly the hint. Filling it in links the spoken count to written digits. Later, it becomes a tool for adding.

When several boxes in a row are empty, a number gets skipped or written twice. One card leaves only the 1. Point to each box and say its number together before typing. Ask, "What comes after the one you just wrote?" Praise the care: "You filled the line without skipping."
