This parent guide supports parents in helping their child at home with the 2nd Grade Math content.

This resource accompanies our Rethink 2nd Grade Math Geometry unit. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning. 

This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 2nd Grade Math in Geometry.

This activity focuses on the part of the standard that says “Recognize that equal shares of identical wholes need not have the same shape.” Students will use 1 inch square blocks to illustrate this statement. After creating their designs and discussing the fractional representations, they will solve and discuss word problems based on this concept. 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.

Sample Learning Goals
Build equivalent fractions using numbers and pictures
Compare fractions using numbers and patterns
Recognize equivalent simplified and unsimplified fractions
Note: Build A Fraction expands on ideas from the Fraction Intro and Fraction Matcher sims or can be used as a stand-alone tool

The Family Letters are intended to be sent home at the beginning and middle of the cluster. They explain big ideas of the cluster using family-friendly language. Families can also find tips for working with their children at home, digital games, videos, and books. This file contains both English and Spanish versions of the Family Letters.

Ck-12's Grade 2 Elementary Math is a series of videos and interactive videos designed to teach basic math concepts to 2nd graders. Concepts covered include Addition and Subtraction, Multiplication, Place Value, Decimals, Time, Fractions, Money, Measurement, and Geometry.

Sample Learning Goals
Find matching fractions using numbers and pictures
Make the same fractions using different numbers
Match fractions in different picture patterns
Compare fractions using numbers and patterns

Sample Learning Goals
Predict and explain how changing the numerator of a fraction affects the fraction's value
Predict and explain how changing the denominator of a fraction affects the fraction's value
Convert between a picture of a fraction, a numeric fraction, and a point on a number line
Build matching fractions using numbers and pictures
Compare fractions using numbers and patterns

G2M8: Time, Shapes, and Fractions as Equal Parts of Shapes. Contains 16 Lessons.

In this lesson, students combine shapes to create a composite shape; create a new shape from composite shapes.

In this lesson, students interpret equal shares in composite shapes as halves, thirds, and fourths.

In this lesson, students partition circles and rectangles into equal parts, and describe those parts as halves, thirds, or fourths.

In this lesson, students describe a whole by the number of equal parts including 2 halves, 3 thirds, and 4 fourths.

In this lesson, students recognize that equal parts of an identical rectangle can have different shapes.

In this lesson, students partition circles and rectangles into equal parts, and describe those parts as halves, thirds, or fourths.

In this lesson, students construct a paper clock by partitioning a circle into halves and quarters, and tell time to the half hour or quarter hour.

This short video and interactive assessment activity is designed to teach second graders an overview of quarter-circles and semi-circles.
