Unit Title | Unit 1: Addition and Subtraction Fluency
| Unit 2: Geometry | Unit 3: Place Value | Unit 4: Addition and Subtraction (2 Digits) |
Time | 14 Days | 14 Days | 26 Days | 44 Days |
Understandings | Students will build upon their 1st Grade foundation of applying basic facts, strategies, and properties of operations to solve addition and subtraction problems within 20. This unit focuses on continuing the use of these strategies to develop fluency and automaticity in basic addition and subtraction facts. | Students will create, sort, and classify two- and three-dimensional figures, as well as compose and decompose geometric figures based on geometric attributes.
| Students will continue to develop an understanding of the base-10 place value system and place value concepts up to 1,200.
Students will compose and decompose numbers using concrete objects, pictorial models, and numerical representations.
Students will use place value relationships to compare and order whole numbers up to 1,200.
Students will use relationships between coins to determine the value of each coin.
| Students will identify situations in which addition and subtraction are useful to solve problems.
Students will develop and use strategies based on place value and properties of operations to add and subtract multi-digit whole numbers.

Understandings | Students will collect, organize, and represent data using bar graphs and pictographs to make it useful for interpreting information.
Students will draw conclusions, make predictions, and write and solve addition and subtraction problems using information from graphs. | Students will identify situations in which addition and subtraction are useful to solve problems.
Students will develop and use strategies based on place value and properties of operations to add and subtract multi-digit whole numbers. | Students will determine the length of an object, describing the inverse relationship between the size of a unit and the number of units needed, representing whole number distances from zero on a number line, and solving problems involving length.
Students will determine that area is a measure of square units that cover a surface.
Students will read and write time to the nearest one-minute increment using digital and analog clocks, and distinguish between a.m. and p.m.
| Students will partition objects into equal parts, name the parts, and compare the sizes of parts.
