Mini Lesson
You did it! You have completed all 40 lessons of Grade 1 Math. Today is Math Fair Day — a chance to show the people you love everything you have learned, and to celebrate how far you have come!
What is a Math Fair?
- A Math Fair is like a science fair — but for math!
- You choose one topic you loved this year and present it to your audience (family members, a friend, or a stuffed animal!).
- You explain the idea in your own words and demonstrate it using drawings, coins, shapes, or anything you like.
How to prepare your presentation
- Choose your topic — pick the math idea or unit that excited you most.
- Make a display — draw a poster, a shape picture, a tally chart, or a shop poster from your worksheets.
- Write three sentences to say out loud: what the topic is, one interesting fact you learned, and why you liked it.
- Demonstrate live — show one skill: count coins, solve a word problem, name shapes, or extend a pattern.
What you have achieved this year
- You can count to 100 and understand place value.

- You can name 2D and 3D shapes and compare measurements.
- You can read tally charts, bar graphs, identify coins, count money, and make change.
