This Roadmap explains to students what area is and how to calculate the area of a quadrilateral. There is various practice nodes and assessments to ensure mastery.
Telling time to the nearest minute and solving time word problems through video, games and quizzes.
Exploring measuring, estimating, and solving word problems involving volume and mass
This short video and interactive assessment activity is designed to teach fifth graders about visually finding weight in compound units.
This short video and interactive assessment activity is designed to give fifth graders an overview of comparison of weights (metric units).
On a hike with her children, Mrs. Thompson noticed the reflection of the top of a pine tree in a puddle in the path. Her son, who is almost a foot taller than she is, could not see the top of the tree in the puddle until he moved. Why did her son need to move to see the top of the tree? How can they use similar right triangles and indirect measurements to find the height of the tree?
7th and 8th Graders learn about Volume and Surface Area using the tool Goose Chase.
Unit 8: Data Sets and Distributions
Lesson 9: Interpreting the Mean as Fair Share
In this lesson, students find and interpret the mean of a distribution (MP2) as the amount each member of the group would get if everything is distributed equally. This is sometimes called the “leveling out” or the “fair share” interpretation of the mean. For a quantity that cannot actually be redistributed, like the weights of the dogs in a group, this interpretation translates into a thought experiment.
Suppose all of the dogs in a group had different weights and their combined weight was 200 pounds. The mean would be the weight of the dogs if all the dogs were replaced with the same number of identical dogs and the total weight was still 200 pounds.
Here students do not yet make an explicit connection between the mean and the idea of “typical,” or between the mean and the center of a distribution. These connections will be made in upcoming lessons.
This lesson will allow students to build their own balloon car racer as an introduction to engineering and coding. Each pair or team of students will be able to engineer their balloon car, measure the performance of their cars using yard sticks, and set up a basic algorithm to construct and run their machine.PURPOSEThe goals for this lesson are to: (1) integrate engineering and coding to young students; (2) have students independenty identify the steps (an algorithm) to build and improve their racers; (4) be able to spot "bugs" in their algorithm; (3) integrate measurement and addition operations to determine which car went furthest overall; and (4) teach perserverance by showing students that it is normal to find bugs in algorithms/coding.

This short video and interactive assessment activity is designed to teach second graders about length comparisons using data tables.
This short video and interactive assessment activity is designed to teach fifth graders about single object length (english units).
This short video and interactive assessment activity is designed to teach first graders about single object length (english measurent).
In this activity students compare objects to see which is longer and heavier than the other.
In this task students figure out how to draw the longest line on a map of the United States without hitting a border. They use color and line plots to keep track of their results.
The purpose of this task is for students to compare two options for a prize where the value of one is given $2 at a time, giving them an opportunity to "work with equal groups of objects to gain foundations for multiplication." This context also provides students with an introduction to the concept of delayed gratification, or resisting an immediate reward and waiting for a later reward, while working with money.
The purpose of this task is for students to find different pairs of numbers that sum to 9.
This instructional task gives students a hands-on experience with composing and decomposing geometric figures.
This task is to introduce students to the concept of reading an analog clock.
The purpose of the task is for students to solve a multi-step multiplication problem in a context that involves area. In addition, the numbers were chosen to determine if students have a common misconception related to multiplication.
