Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, ..., and represent whole-number sums and differences within 100 on a number line diagram.
General Information
Subject Area: Mathematics
Grade: 2
Domain-Subdomain: Measurement and Data
Cluster: Level 2: Basic Application of Skills & Concepts
Cluster: Relate addition and subtraction to length. (Major Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Formative Assessments

Representing Numbers with Length:

Students are asked to find a number that was represented by a length on an incomplete number line.

Type: Formative Assessment

Representing Nine on the Number Line:

Students are asked to scale a number line and use it to draw a segment of length nine.

Type: Formative Assessment

Differences on a Number Line:

Students use a number line to find to the difference between 17 and 42.

Type: Formative Assessment

Sums on a Number Line:

Students use a number line to add 23 and 19 and to find a segment whose length is the sum of 23 and 19.

Type: Formative Assessment

Lesson Plan

Get Up and Go! with Addition and Subtraction:

The lesson involves students adding and subtracting on a number line while follwoing a story that explains the amount of time taken to get ready in the morning. Students will write addition and subtraction equations to represent the parts of the story.
