SALTA 1st Grade Curriculum Map

Reason abstractly and quantitatively. Make sense of quantities and their relationships in problem situations. Contextualize quantities and operations by using images or stories. Decontextualize a given situation and represent it symbolically. Interpret symbols as having meaning, not just as directions to carry out a procedure. Know and flexibly use different properties of operations, numbers, and geometric objects. First grade students use reasoning as they think about how numbers in word problems are related. Listen and look for students that exhibit the following behaviors: • identify and understand the quantities in the problem • show and explain how quantities are related • translate real-world contexts correctly to numbers, expressions, equations, or concrete or pictorial representations • connect numbers, expressions, equations, or concrete or pictorial representations back to real-world contexts.

Topic 4:

First grade students will understand and apply properties of operations and the relationship between addition and subtraction. Standard 1.OA.3 Apply properties of operations as strategies to add and subtract. For example: If 8+3 = 11 is known, then 3+8 = 11 is also known. (Commutative property of addition.) To add 2+6+4, the second two numbers can be added to make a ten, so 2+6+4 = 2+10 = 12. (Associative property of addition.) First grade students need not use formal terms for these properties. Standard 1.OA.4 Understand subtraction as an unknown-addend problem. For example, subtract 10-8 by finding the number that makes 10 when added to 8.
