These posters are great for anchor charts, interactive notebooks, math centers, math workshop, digital learning notes, and graphic organizers.

In the book, Number Talks Matter, five main addition strategies are explained in chapter six to use when solving addition problems mentally. The book is great because it explains many different strategies for mentally breaking down and solving problems with all operations involving whole numbers, decimals, and fractions.

(See my free digital download "Addition Number Talks" that has approximately 60 addition problems to try these strategies.)
