During first grade, students will participate in a math program called Story of Units.  The Story of Units consists of 6 modules.  You may click on the link below to view each module.

 

Grade 1 Module 2:  Introduction to Place Value Through Addition and Subtraction Within 20

Module 2 serves as a bridge from students' prior work with problem solving within 10 to work within 100 as students begin to solve addition and subtraction problems involving teen numbers. Students go beyond the Level 2 strategies of counting on and counting back as they learn Level 3 strategies informally called "make ten" or "take from ten."

We will begin Module 2.  Module 2 builds on Module 1; however, the sums and differences increase to 20 instead of 10.

Overview of Module 2:

***Topic A begins with students solving word problems with three addends (1.OA.2) as a way for them to begin to explore the make ten Level 3 strategy in a meaningful context. 

Topic B focuses on the take from ten Level 3 strategy (1.OA.6). Students begin with word problems calling on them to subtract 9 from 10 in Lessons 12 and 13, first with concrete objects, then with drawings, and then with number bonds.

Topic C provides students with practice solving add to with change unknown, take from with change unknown, put together with addend unknown, and take apart with addend unknown word problems (1.OA.1)

Topic D closes the module with students renaming ten as a unit: a ten. 

 

We will continue the 1st grade Module 1 Story of Units.  This unit focuses on fluency (speed with accuracy) with additon and subtraction of numbers to 10.  We will use addition and subtraction to solve word problems.  Students will use number bonds to help them build this fluency. 

We will continue to explore and understand number bonds up to 10.

 

We will continue our Story of Units module on number bonds and strategies to build our fluency with addition to 20.

 

 

Module 1

We will review math skills taught in kindergarten.  This will include understanding subitizing, five and ten groups, and number bonds.
