Students add and subtract within 10, and represent and interpret categorical data.
In this unit, students deepen their understanding of addition and subtraction within 10 and extend what they know about organizing objects into categories and representing the quantities.
October-November
Approx. 22 Days
Students solve new types of story problems within 10 using the relationship between addition and subtraction. They develop an understanding of the meaning of the equal sign and connect story problems to equations.
In this unit, students learn to solve new types of addition and subtraction story problems and relate the quantities in the stories to equations.
Here, students encounter most of the problem types introduced in grade 1: Add to/Take From, Change Unknown, Put Together/Take Apart, Unknowns in All Positions, and Compare, Difference Unknown. The numbers are kept within 10 so students can focus on interpreting each problem and the relationship between counting and addition and subtraction. This also allows students to continue developing fluency with addition and subtraction within 10.
December- January
Approx. 28 Days
Students add and subtract within 20. Students apply the properties of operations and the relationship between addition and subtraction.
In this unit, students develop an understanding of 10 ones as a unit called “a ten” and use the structure of 10 + n to add and subtract within 20.
Here, students decompose and recompose addends to find the sum of two or three numbers. For example, to find the value of 9 + 6 , they may decompose 6 into 1 and 5, compose the 1 and 9 into 10, and find 10 + 5.
January/ February
Approx. 23 Days
This unit develops students’ understanding of the structure of numbers in base ten, allowing them to see that the two digits of a two-digit number represent how many tens and ones there are.
March
Approx. 14 Days
Students use place value understanding and properties of operations to add within 100
In this unit, students add within 100, using place value and properties of operations in their reasoning.
April-May
Approx. 17 Days
Students measure length and count up to 120 length units. They solve addition and subtraction story problems with unknowns in all positions.
In this unit, students extend their knowledge of linear measurement while continuing to develop their understanding of operations, algebraic thinking, and place value.
May - June
Approx. 17 Days
Students reason with shapes and their attributes, partition shapes into equal pieces, and tell time to the hour and half hour.
In this unit, students focus on geometry and time. They expand their knowledge of two- and three-dimensional shapes, partition shapes into halves and fourths, and tell time to the hour and half of an hour. Center activities and warm-ups continue to enable students to solidify their work with adding and subtracting within 20 and adding within 100.
End of Course Assessment
End of Course Assessment
This assessment is optional. Students consolidate and solidify their understanding of concepts and skills in this unit. The unit assessment for this unit is a "Year in Review." Use portions that are relevant.
In this unit, students revisit major work and fluency goals of the grade, applying their learning from the year.
In Section A, students add and subtract within 20, concurrently working toward the goal of adding and subtracting fluently within 10. In Section B, they practice solving story problems of familiar types (those introduced in earlier units). In Section C, students count and represent numbers within 120.
