Level 1: Sharing and "for every"

Ratio, rates and money · level 1 of 8 · rough age 5-6 (a guide for parents; anyone can start anywhere)

Ratio starts with two everyday ideas: sharing fairly, and things that come in groups ("2 wheels for every bike"). In this level you deal out snacks so every plate is the same, count by groups, make a recipe twice so it still tastes right, and meet the coins of Canada and use them in a play shop. Every lesson has pictures, things to try with real objects, and answers to check.

Lesson	You will be able to
Fair shares	Share things fairly by dealing one at a time, explain why dealing is always fair, and check a share by counting
"For every"	Count things that come in groups by twos, threes, fours and fives, and work backwards from the total to the number of groups
Doubling a recipe	Double or triple every ingredient of a recipe, and explain why forgetting one changes the taste
Canadian coins	Name the nickel, dime, quarter, loonie and toonie and their worth, and explain why a smaller coin can be worth more
Shopping play	Pay for toys with loonies and toonies, tell which costs more, and decide what you can afford
