Operations and Algebraic Thinking

Goal P-MATH 6. Child understands addition as adding to and understands subtraction as taking away from.

• Represents addition and subtraction in different ways, such as with fingers, objects, and drawings.

• Solves addition and subtraction word problems. Adds and subtracts up to five to or from a given number.

• With adult assistance, begins to use counting on from the larger number for addition. For example, when adding a group of three and a group of two, counts "One, two, three…" and then counts on "Four, five!" (keeping track with fingers). When counting back for subtraction such as taking away three from five, counts, "Five, four, three…two!" (keeping track with fingers).

Goal P-MATH 7. Child understands simple patterns.

• Fills in missing elements of simple patterns.

• Duplicates simple patterns in a different location than demonstrated, such as making the same alternating color pattern with blocks at a table that was demonstrated on the rug. Extends patterns, such as making an eight block tower of the same pattern that was demonstrated with four blocks.

• Identifies the core unit of sequentially repeating patterns, such as color in a sequence of alternating red and blue blocks.
