In this lesson students evaluate expressions and consider how the Order of Operations changes the value of the expressions. 

In this lesson students explore how new shapes can be formed by composing other shapes. This is remixable , especially to add various supports to meet the needs of all learners.

In this lesson, students learn the attributes of triangles by constructing them from various side lengths.

In this lesson, students explore various triangles by sorting them based on attributes such as having equal lengths and square corners (right angles).

In this lesson, students explore various quadrilaterals by sorting them based on attributes such as opposite sides having equal lengths and square corners (right angles).

In this lesson, students identify and explain the attributes of a quadrilateral and use defining attributes (number of sides, angles) to name quadrilaterals.

This lesson uses the area model to support students' work with adding fractions with unlike denominators. This is remixable if you add ideas to support the range of learners.

This lesson uses the area model to support students' work with adding fractions with unlike denominators. This is remixable if you add ideas to support the range of learners.

*Additional resources were added to provide an online component for students to create an area model.

This lesson provides opportunities for students to compare and order decimals, add and subtract decimals, and estimate the reasonableness of sums and differences of decimals. This is remixable if you add additional supports for the range of learners.

This lesson allows students to explore and make sense conceptually of the order of operations. This is remixable if you provide additional supports for the range of learners.

In this lesson, students will use nautical flags to apply their understanding of addition and subtraction of fractions with unlike denominators within context. This is remixable if you provide additional supports for the range of learners.

In this lesson, students solve a word problem using a strategy of choice and share the strategy to develop the concept of representing and solving problems involving addition and subtraction within 20. This problem type will likely provide an opportunity to explore the commutative property with students. This lesson format may be used with any problem type appropriate for the grade.

This resource is from Tools4NCTeachers. In this lesson, students develop strategies for adding 3-digit numbers, with a focus on adding in chunks.  Students build this strategy of adding in chunks by mentally adding 10 and 100 to numbers, and adding on the number line. Remix this lesson to include extension activities such as math stations.

This lesson should occur after the Partner Quick Flash lesson, which introduces conceptual subitizing. Candy Quick Flash continues to encourage conceptual subitizing an efficient way to find "how many".

Notes:
Perceptual subitizing: instantly recognizing "how many" in a set
Conceptual subitizing: efficiently finding "how many" by recognizing and combining subgroups within a set
