This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: How does the value of a fraction change if you double its numerator? Explain your answer. How does the value of a fraction change if you double its den...
In this lesson, students will work together to figure out how many pencils the teacher will need to buy for the year. This lesson is a culminating task for Numbers and Base Ten and will incorporate rounding and multiples of ten.
This resource is from Tools 4 NC Teachers. In this lesson, students will play a game and see multiplication as combining equal groups, use repeated addition and other strategies to find the total number of stars, and record answers by writing equations.
This lesson is from Tools 4 NC Teachers. It was written with the intent that it would be taught on Day 10 of Cluster 1. In this lesson, students explore the concept of multiplication by thinking about things that come in groups. They connect equations to story problems that involve equal groups, use various strategies to solve those problems, and share their thinking by communicating their reasoning and sharing solutions.
This lesson is from Tools4NCTeachers. It was written with the intent of being taught on Day 7 of Cluster 1. This lesson focuses on repeated addition and skip counting to provide a conceptual understanding of multiplication. The lesson also provides opportunities for teachers to discuss the role of collaboration with classmates.
This lesson is from Tools 4 NC Teachers. This lesson focuses on repeated addition and identifying errors in skip counting. The activities provide opportunities for teachers to discuss the role of dealing with errors while establishing a classroom community of mathematicians.
This resource is from Tools 4 NC Teachers. It provides several number talks for teachers to do with their students. The content aligns with Grade 3, Cluster 1. In the notes section there are suggestions for doing the Number Talk with students. The resource can be remixed!
This lesson is from Tools 4 NC Teachers. It was written with the intent that it would taught on Day 8 of Cluster 1. This is lesson focuses on repeated addition and a conceptual understanding of multiplication. As students act out and draw representations to solve math problems, the idea that mathematicians draw pictures and use tools such as number lines to help them solve problems is reinforced.
This lesson is from Tools4NCTeachers. In this lesson, students look at patterns between numbers and their multiples by creating multiple towers. They will use these relationships of related facts, along with properties of operations to solve multiplication problems involving multiples of ten. This is remixable.
In this lesson students explore arrays through the context of flats of flowers. Students determine the total number of flowers and write an equation using equal addends. Students calculate the total cost of flats of flowers within 99¢ and represent cost with variations of quarters, dimes, nickels, and pennies.
