Here is a cutie poster I made up for the lesson.
We started off playing Triangular Cards.
Then we moved into looking into more what it means when I know one sum, then I get 3 more for free! Children pulled out a fact family card and write the 4 sums they could make using those numbers.
When the children were finished, they rolled 2 x 20 sided dice then added those numbers together to make the third number. Then we wrote the 3 other sums we get for free!
I got this reflection idea from Top Notch Teaching - children drew either 1, 2 or 3 sides of triangle depending on how they thought they went today.
You can download your own Fact Family Triangles from this pack, including a 3 for Free poster!
