This Arithmefacts game was shared by Dianne Ogle.
It is a game for 2 to 4 players where students use operations to make equations which equal each other. Each player practices forming equations when other players put their cards down and they may have to explain their working if they are challenged.
This resources has instructions and game cards included.
Suitable for curriculum level 2 – 5.
Noel Johnston, Kaiarahi for Otago, Southland has put together this word document of a range of starter problems for teachers to use to get their kids thinking. There are some lovely problems here, some need some unpacking and some can be extended, feel free to use them.

There are 5 sets of cards in this sequence starting from A through to E.
Within each set, there are 4 cards. The sum of the answers to all 4 cards is recorded at the bottom of the page. If you take out the card with the dot, the sum of the other 3 cards will give a different answer which is also recorded at the bottom of the page.
You can get students into groups of 3 or 4 and they each solve one question each. Only when all group members have worked out their answer do they know if they are correct.
They can start at Set A and progress through the sequence.
A: Fraction of a number – where 1 is the numerator
B: Fraction of a number – where the numerator is not 1
C: Fraction of a number – word problems
D: Fraction of a number – word problems and one adding on
E: Fraction of a number – word problems and one finding what’s left
