Product Description

First Grade Common Core Math Units

*************************************************************

Intro to Numbers and Operations in Base Ten for First Grade

Intro to Measurement and Data for First Grade

Intro to Geometry for First Grade

*************************************************************

This interactive presentation covers all the standards for first grade Common Core Operations and Algebraic Thinking mathematics. The compressed folder contains the presentation in both PowerPoint and SmartBoard format (16:9 View). The lessons can be used to introduce the concept, reinforce the concept, or review the concept. It would also be excellent when you are being observed to display the fact that you are working on implementing the Common Core mathematics standards. Second grade teachers could use the presentation as a review at the beginning of the year. This product works best if the teacher computer is connected to a projector, or the teacher has access to a room with a computer connected to a projector. Multiple examples are used for each standard. An answer key is also included.

Common Core Standards for First Grade

Operations and Algebraic Thinking

• CC.1.OA.A.1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

• CC.1.OA.A.2 Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

• CC.1.OA.B.3 Apply properties of operations as strategies to add and subtract.2 Examples: 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.)

• CC.1.OA.B.4 Understand subtraction as an unknown-addend problem. For example, subtract 10 - 8 by finding the number that makes 10 when added to 8.

• CC.1.OA.C.5 Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).

• CC.1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
