In school in every maths lesson, we start by counting forwards and backwards from different numbers. Today I would like you to count forwards and backwards in 2s from 60.
Today you are going to play a game using your addition and subtraction knowledge.
Challenge - see if you can work out the answers mentally.
Watch the video below for instructions or follow the written instructions.
Start off by drawing a number line 0-20.
The first player chooses a number on the line and crosses it out.
The same player then chooses a second number and crosses that out too.
Finally, he or she circles the sum or difference of the two numbers and writes down the calculation. You can choose whether you add or subtract however, it must equal an answer on your number line.
The second player must start by crossing off the number that player 1 has just circled.
He or she then chooses another number to cross out and then circles a third number which is the sum or difference of the two crossed-off numbers.
Player 2 also writes down their calculation.
For example, once the second player has had a turn, the game could look like this:
Play continues in this way with each player starting with the number that has just been circled.
For example, player one could then have a turn which left the game looking like this:
The winner of the game is the player who stops their opponent from being able to go.
Now it's your turn!
Try playing the game a few times to get a feel for it.
What is your strategy for winning?
Flaming hot - to make it more difficult, maybe your number line could go up in 3's, 4's etc.
