Math

In Unit 1 of Math Expressions, students will be finding 1 more and 1 less patterns with counting numbers, then with finding partners, and finally with addition and subtraction.  The repeated experiences in Unit 1 is a bridge from Kindergarten experiences to the embedded addends required in Unit 2 for counting on. 

Unit 2

Students will begin to recognize addition and subtraction problem types and write equations to represent addition and subtraction situations. Students will discuss and recognize if equations are true or false and relate addition to subtraction.

Unit 3

This unit focuses on unknown partners represented as both addition and subtraction situations. We will write both equations and answers with labels for word problems.  We will continue to practice fluency within 10.

Unit 4

In this unit students will work with teen numbers and explore tens and ones using physical groupings and math drawings. Activities will provide practice with building 2 digit numbers.  Students will use place value concepts while adding with 1 and 2 digit numbers.

Unit 5

This unit extends the strategies that appeared in Unit 4 for unknown parners in addition and subtraction situations. The strategies of counting on and making a ten to find totals within 20 appear in this unit. Students will use prior knowledge to solve problems with greater numbers by using familiar problem types, models and drawings.

Unit 6

In this unit students use what they know about sorting and classifying to sort and display data.  They build on what they know about comparing numbers to develop comparison statements for a set of data.  In this unit we will focus on the vocabulary more and fewer to compare and use comparison bars.

Unit 7

This unit builds on the geometry and measurement concepts and knowlege that students previously learned.  The focus will be on composing  and decomposing shapes.  Students will explore 2 and 3 dimensional shapes, properties of shapes, and equal shares.  Measuring time is also included in this unit.  Students will work with both analog and digital clocks.

Unit 8

In this unit, students use modeling skills and addition concepts to add with 2 digit numbers when grouping a ten is and is not required.  Students will also practice subtracting 2 digit numbers.
