This parent guide supports parents in helping their child at home with the 1st Grade Math content.

This resource accompanies our Rethink 1st Grade Math Number & Operations in Base Ten 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 1st Grade Math for Number & Operations in Base Ten.

Students view and practice ways to add whole tens mentally or using models, drawings, and strategies based on place value.

This lesson is for Grades 1 - 2 on math. At Home Learning Lessons are a partnership between the North Carolina Department of Public Instruction, PBS North Carolina, and the William and Ida Friday Institute for Educational Innovation.  Each lesson contains a video instructional lesson, a PDF lesson plan with a transcript, and a PDF file of extension activities.

First grade students will work in small group settings to discover how to become an architectural engineer. They will research and demonstrate their knowledge of bridge designs through STEM and drawings. Finally developing a strong infrastructure that will collaboratively fit onto a created setting. Allowing them to present a model of their findings.

The Family Letters 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.

For this assessment, students are asked about what they would purchase at the store given a set amount of money and prices.

In this assessment, students demonstrate their ability to use place value understanding and properties of operations to add and subtract, as well as represent and solve problems involving addition and subtraction.

Sample Learning Goals
Improve understanding of place value by using different sizes of papers for ones, tens, and hundreds.
Develop mental math strategies when taking apart and putting together numbers.
Use the “make a ten” strategy when counting and doing addition.
Develop a mental model of the basic properties of numbers including commutativity, associativity, and closure.

Students will decide on a concrete model for subtracting multiples of 10 in the range 10-90 and will create an instructional video. 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 document is the About the Cluster document created by the authors of the NC2ML Instructional Frameworks. Read this document prior to teaching the cluster in order to get insight into the clustering of the standards, mathematics to be taught, and important considerations.

This short video and interactive assessment activity is designed to teach first graders an overview of subtraction (numbers to 100).

This is a problem-solving task focused on recycling.  The number range is multiples of 10 from 100 – 190. Students solve word problems and write a word problem. Extra questions about recycling are included. 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.

Students represent a given number with Base Ten blocks, take away 10 and record the new number. Students continue doing this until they reach the number 12. Then students choose another 2-digit number between 75 and 89 repeating their initial steps in efforts to get a number as close to zero as possible.

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.

The intended purpose of this document is to provide teachers with a tool to determine student understanding and suggest instructional moves that may help guide a student forward in their learning. It is not an exhaustive list of strategies.

Students do research to uncover some interesting fact in an area of study that involves a 2 – 4 digit number.  Students design a four or five-step mental math problem for each other.  They take turns trying to follow the steps mentally and arrive at the partner’s number.  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.
