6514465-470535Revision DateApril 20, 202000Revision DateApril 20, 2020Department of Curriculum & InstructionFirst Grade Math Unit1-4 Addition and Subtraction to 20Time Frame10/19-11/13Big IdeasNumber relationships are the basis for addition facts. Addition and subtraction have an inverse relationship, which can be used to find subtraction facts. Information in a problem can be shown using a picture or diagram. Problems can be solved by writing and completing a number sentence. Essential QuestionsHow can you use doubles facts to help find the sums of other numbers? How does knowing an addition fact help find the answer to a subtraction fact? How do you know what information to use from a problem to help draw a picture to solve?

However, daily exposure and repeated independent practice (spiraled stations) are necessary for students to meet the rigor of this TEK when they are in second grade (TEK 2.4A).

Partnering students in stations allows them the opportunity to talk about their mathematical thinking, apply academic vocabulary, and hear how their peers think about math. When students visit math centers, the teacher has the opportunity to meet with Guided Math groups for small group instruction. Once stations are created and introduced, they can be spiraled back and utilized in any unit.
