Grade 3 Curriculum
The full sequence of Grade 3 units, in coherence order. Units without a link yet are still being built.

Introduces the standard place value algorithms for addition and subtraction and deepens an understanding of place value to three and four places.

Introduces multiplication by building sequentially from repeated addition to partial products on the open number line and builds strategies for automaticity of the basic facts.

Introduces the ratio table as a powerful tool for multiplicative reasoning and lays a foundation for the development of proportional reasoning and the use of partial products.

Develops the open array model that can be used as a powerful tool to support the development of partial products and the distributive, commutative, and associative properties.

Designed to promote mathematical inquiry on area and perimeter by decomposing and rearranging, and to support students' growing understanding of the properties of multiplication.

Designed to promote mathematical inquiry and to encourage children to become excited about being a mathematician.

Introduces the use of two marked dimensions, effectively turning value bar comparisons and line plots into more readable graphs. Scales are also extended to include fractions and scaled data.

Concepts are explored in the context of walking and feeding 9 dogs. Students build connections between the operations of multiplication and division as they develop a feeding chart for the dogs and engage in minilessons.
