This parent guide supports parents in helping their child at home with the 4th grade Math content.

This resource accompanies our Rethink 4th Grade Math course. 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 short video and interactive assessment activity is designed to teach fourth graders about adding decimals - word problems.

This short video and interactive assessment activity is designed to teach fourth graders about adding and subtracting.

This short video and interactive assessment activity is designed to teach fourth graders about addition: completing the addition sentence.

This short video and interactive assessment activity is designed to teach fourth graders about calculating distance in meters.

This short video and interactive assessment activity is designed to teach third graders about creating largest and smallest numbers given digits.

This lesson is for Grades 4-5 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.  

Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful human-made CFCs (chlorofluorocarbons).

Working as if they are engineers who work for (the hypothetical) Build-a-Toy Workshop company, students apply their imaginations and the engineering design process to design and build prototype toys with moving parts. They set up electric circuits using batteries, wire and motors. They create plans for project material expenses to meet a budget.

This activity focuses on the importance of using mathematics to find deals when grocery shopping.  Students will analyze data from local grocery store advertisements and determine the best deals by using multiple strategies.  This task will also require students to find and compare unit rates, which connects the fourth grade concepts of solving problems involving money and using place value understanding to do arithmetic to the sixth grade standard of determining a unit rate.  Once students find which store offers the best deal, they will create a public service announcement teaching others how to find the best deals when grocery shopping. This public service announcement is an opportunity to use precise mathematical language and construct viable arguments.  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 lesson introduces students to `while` loops and `if / else` statements. _While loops_ are loops that continue to repeat commands as long as a condition is true. While loops are used when the programmer doesn't know the exact number of times the commands need to be repeated, but the programmer does know what condition needs to be true in order for the loop to continue looping. `If / Else` statements offer flexibility in programming by running entire sections of code only if something is true, otherwise it runs something else.

In this lesson students learn to figure out elapsed time by counting, subtracting and regrouping in base 60. This activity is motivated by a Cyberchase episode in which Digit and Hacker compete in a cooking contest.

This document provides sample performance tasks/assessment items for Common Core State Standards Grade 4 Math provided by the Louisiana Department of Eduation. Both questions and exemplary responses are included.

This is a story about a potato…not any type of potato though. A potato who sits in the exact same spot on the couch every day using all of his devices (tv, phone, video games, etc). It’s a perfect life until the power goes out one day, and he has to find other things to do. He learns that he needs to have a balance between screen time and activities in the real world. Your job as an engineer is to design a gadget that will remind the potato when he needs to ditch the screens and get up and move. (You must incorporate your iPad.)

This resource will have you make a clone of a Go Formative document. This is a free website where teachers and students can interact digitally.

This project creates a classroom tool that can be used throughout the year. Color-coded strips of paper represent ones, tens, hundreds, and all the way up to millions.

The goal is for students to understand the basics of engineering that go into the design of a sneaker. The bottom or sole of a sneaker provides support, cushioning, and traction. In addition the sole is flexible and can have some fashion based functions such as cool colors and added height. The sneaker is a well-engineered product, utilizing a variety of materials to create a highly functional, useful shoe. This unit focuses on having the students select specific design requirements, such as good traction or lots of cushioning, and then select from a variety of materials to build a model shoe with the same design criteria.
