Show and Tell: Counting Our Toys to 20
Today is Show and Tell day! You brought your favorite toy cars to class. Your teacher says, "Before you tell us about them, count them!" You line up 14 cars in a row and touch each one as you count: 1, 2, 3... all the way to 14.
What You'll Learn
- Count objects one by one, all the way up to 20 - Line up items in a row so none get skipped or counted twice - Compare two groups of objects to see which has more - Tell a short number story about your own toys
One Touch, One Number
When you count, each object gets exactly one number — no more, no less! If you have a pile of crayons, touch the first one and say "1," touch the next one and say "2," and keep going. This is called one-to-one counting, and it's the most important counting rule of all.
Lining Up So Nothing Gets Missed
Counting a messy pile is tricky — it's easy to count the same toy twice or skip one by accident! The fix is simple: line your toys up in a neat row first, then count from left to right, touching each one exactly once.
Move each toy to a new pile as you count it. Once a toy has moved to the "counted" pile, you know for sure it's already been counted!
Which Group Has More?
At Show and Tell, Maya brought 9 rocks and Jayden brought 12 seashells. Who has more? Jayden does! We can even say exactly how many more: 12 take away 9 leaves 3, so Jayden has 3 more shells than Maya has rocks.
Maya counted 9 rocks and Jayden counted 12 shells. How many more shells does Jayden have than Maya has rocks?
What is the best way to make sure you don't count the same toy twice?
Your Own Show-and-Tell Count
Pick 15 to 20 small objects at home, like buttons, blocks, or spoons. Line them up in a row. Count them out loud while moving each one to a new pile, then write down the total number. Ask a family member to count a different small group of objects, then write down which group has more and exactly how many more.
