Students use manipulatives to represent visually the steps they take to obtain a solution to an algebraic equation. They develop an understanding of the connections between the solution involving manipulatives and the symbolic solution.

This lesson is Day 8 in a series of 12 lessons around fraction equivalences and comparisons.

This video lesson introduces the number as a tool for representing and comparing fractions. Students will need a black piece of a paper and a pencil with a good eraser.

This video shows HOW and WHY we can shift decimals to make whole numbers when dividing.

This lesson will provide students with an introduction to solving equations and inequalities numerically (using a table), graphically, and algebraically.

This Thinglink provides a series of brief videos addressing a) common areas of difficulty related to problem solving and b) an overview of additional and subtraction problem types.

This video has been created by NCDPI. It provides tips for integrating reading within the math block.

This resource is from Tools4NCTeachers.In this lesson the students are introduced to measuring length with standard units as they attempt to create a bed for a queen. They will also measure the length of an object in both inches and centimeters.

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 lesson is from Tools4NCTeachers.In this lesson, students use a measuring tape to measure, record, and compare the lengths of their arm spans. Remix this lesson to include pictures of students in action!  

In this lesson, students use manipulatives to explore addition and subtraction situations.  Math centers and center materials are also provided with this lesson.  

This resource is from Tools4NCTeachers.A Common Formative Assessment (CFA) provides a snapshot of current student understanding. It serves as a checkpoint, and may be used to guide future whole and small group instruction. This CFA addresses 2nd grade, Cluster 6 standards.

This purpose of this lesson is to give students the opportunity to problem solve and analyze other student solutions while working on adding two-digit numbers. This lesson assumes students have had previous experience with multiple addition strategies and that the class has posted strategy supports.

This resource is from Tools4NCTeachers.  In this lesson, students will create a survey question, collect data, create a bar graph, write and answer questions about the collected data.  This lesson may take two days to complete.  Printable, samples of student work, sample anchor charts, and extension ideas are included within this lesson.

This lesson is part of Tools4NCTeachers.  In this lesson, students will use manipulatives to solve addition problems within 10 that involve putting together two groups of objects.  Please remix this lesson to include extensions, additional problems, or samples of student work.
