Making all the combinations to 10

Here we have are answering our problem: " If we have 10 felts. Some are red and some are blue. How many different combinations could we have?" Together we found different combinations and then created a model of our thinking using the red and blue multilink cubes. - Emily and Liam said the multi-link pattern looked like stairs - Can you see this? This activity helps us see what numbers make 10, this is very useful for lots of mathematics questions. We are practicing this a lot!
