This resource is from the North Carolina Collaborative for Mathematics Learning (NC2ML). It may not be remixed.This research brief outlines the Launch, Explore, Discuss lesson structure and the benefits to using this framework.  Many of the Tools4NCTeachers lessons follow this structure.

This is a teacher resource that shows activities for students to decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).

This unit of 1 number and operation lessons explores addition and subtraction on the number line. The unit contains 3 activities.

Students solve addition word problems with numbers up to 18 in this interactive resource.

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.

Students will create and solve word problems using a rock collector theme. This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.

This word problem may be used for instructional or assessment purposes, depending on where students are in their understanding of addition and how the teacher supports them.

Students gain experience and practice with three types of word problems using the "Take From" context: result unknown, change unknown, and start unknown.

This short video and interactive assessment activity is designed to teach second graders about subtracting one-digit numbers - word problems.

This short video and interactive assessment activity is designed to teach second graders an overview of subtraction (numbers up to 20).

This is a video and interactive assessment activity designed to help first graders learn about subtraction word problems up to twenty.

This course features a video review and an assessment practice of subtracting by crossing out with pictures for word problems. It is aimed at first grade math students.

In this Khan Academy interactive, students will use a variety of representations such as objects and pictures to represent subtraction within 10.

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.
