This activity requires some subtraction cards, paper kites, and sky ladders.

Divide the class into small groups
to make teams A, B, C, … Team A Team B Team C Team D

Each team will make a paper kite
and decorate it.

Put the subtraction cards in a box

and fix the sky ladders for each
team on the board or wall.

Attach the kite of each team at the 6 2 3 3 3 5 3 6 3 8 5 9
bottom of the sky ladder. – 1 1 – 3 0 – 2 4 – 1 9 – 3 – 3 5
5 1
Students of each team, one by one, 3 2 9 3 8 5 5 6 3 8 3 5

take turns to pick a subtraction – 8 – 7 5 – 4 0 – 1 8 – 2 3 – 2 8
card and solve the problem.

(For example: 62 – 11 = 51)

the answer is correct, their kite moves up 1 level. If they can explain
If
how they solved it (for example: “I borrowed from the tens place”),

they move up 2 levels as a bonus!

The team whose kite is the first to reach the top of the ladder (Level 10)

wins!

Celebrate with a “Kite Flyer Champion” certificate or a small prize.
