Fair Shares

What your child learns

• Understanding that sharing fairly means equal parts: telling a cake cut into two equal parts from one cut into a big and a small part
• Sharing 6 cookies equally between 2 friends and among 3 friends
• Recognizing one half, one third and one quarter in circles, squares and rectangles cut into equal parts
• Seeing that a shape cut into 4 parts that are not equal is not cut into quarters

How to play

1. Press "Play now". First, tap the cake, pizza or square rice cake that is cut into two equal parts. On a computer, keys 1–4 work too.
2. For cookies, drag each cookie from the jar onto a friend's plate, or tap a cookie and then a friend. A fair share counts as soon as it is done; press "Done" to check. On a computer, use Tab and Enter.
3. For "what part is colored?", count how many equal parts the shape has, then pick "one half", "one third" or "one quarter".
4. For coloring, tap a part of the shape that is cut the right way, for example "Color one quarter of the circle".

For parents

• When you share fruit or a snack at home, ask "Are these two parts the same size?" and let your child share food for the family.
• The Vietnamese version uses the school terms "một phần hai" (one half), "một phần ba" (one third) and "một phần tư" (one quarter), as taught in Vietnamese grade 3 maths. The answer cards also show 1/2, 1/3 and 1/4.
• Unequal cuts in the game are always clearly unequal (the smallest part is less than 6/10 of the biggest), never "nearly equal".
• Pressing "Done" while cookies are still in the jar only gives a reminder and is not counted as wrong. A wrong pick is locked and counts only once; getting it right the first time earns a star.
