I start out by using the big diamond cards and discussing the different strategies students could use to add the four addends. Let students lead the discussion in how they would solve the problems.
Then I put one set of color coded cards up around the room and students get an answer sheet and write the color of the cards for that day. They then add the numbers on the card in a strategy that works for them. Answers are recorded on the worksheet
provided in this product.
Answer keys for the worksheets and activity cards are included. Answers for the practice cards are not included.
I do one set of cards when we are on adding 3 or more addends. Then I get another set out when I want them to review the strategies. Five sets usually last the whole year
