Number Madness with Joel

My maths game was called Number Madness. The object of the game is to have the highest number at the end. I had to count backwards and forwards in 10s, 100s and 1000s. I enjoyed this game.

I Spy with Regan

I played the maths game called "I Spy - Addition", it is a card game. When I add 9 plus 3 I calculate a number to 10 first (9 plus 1) and then I add on the difference of 2 to get the correct answer of 12. My strategy was to make it harder for Paula to find the cards so I added 2 cards together that were placed diagonally on the table.

Alana plays Guess My Number

Today in my maths learning I played a game called Guess My Number. Paula wrote a secret number down on a piece of paper and I had to try and guess it! My strategy was to ask questions like "Is the number odd or even?" and the answer was "Even". "Is it between 200 and 400?" and the answer was "Yes". Now I was able to say if it was between 200 and 300 and I kept asking questions until I narrowed it down and guessed the correct answer which was 268.
Now it is my turn to write down a secret number for Paula to guess.
