Addition and Subtraction
Printable Parent Letter
Students need to:
- Explore the concept of addition by using part-part-whole story mats (add to five, add to ten).
- Explore addition and subtraction with objects, fingers, mental images, drawings, sounds (i.e. claps), acting out situations, or verbal explanations.
- Model story problems involving the joining together of two sets and then describe how many (add to five, add to ten).
- Decompose numbers up to 10 into pairs in order to find the missing part within a whole quantity (part-part-whole mat) (subtract from ten).
- Model story problems involving the separation of a quantity from a larger quantity and then tell how many (subtract from five, subtract from ten).

Ways Parents Can Help
- Practice adding by acting out story problems that involve joining two groups of objects using things around the house.
(i.e a group of 3 red grapes and a group of 3 green grapes – when we put them together, how many grapes do we have in all?)
- Practice subtracting by acting out story problems that involve the separation of a certain number of objects from a larger quantity of those objects by using things around the house.
(i.e I have a group of 8 red grapes and I take 3 away. How many grapes do I have now?)
