This short video and interactive assessment activity is designed to give fourth graders an overview of rounding decimal numbers.
This short video and interactive assessment activity is designed to give fifth graders an overview of rounding decimal numbers.
Students practice rounding whole numbers with this task.
This short video and interactive assessment activity is designed to teach second graders about rounding to the nearest 2 decimal places, or the hundredths place.
The purpose of this task is for students to compare two fractions that arise in a context. Because the fractions are equal, students need to be able to explain how they know that.
This word problem asks students to think about fractions.
This task involves fraction multiplication and can be solved with pictures or number lines.
The purpose of this task is to have students add fractions with unlike denominators and divide a unit fraction by a whole number.
In this challenging instructional task students relate addition and subtraction problems to money and to situations and goals related to saving money.
Students learn how different characteristics of shapes—side lengths, perimeter and area—change when the shapes are scaled, either enlarged or reduced. Student pairs conduct a “scaling investigation” to measure and calculate shape dimensions (rectangle, quarter circle, triangle; lengths, perimeters, areas) from a bedroom floorplan provided at three scales. They analyze their data to notice the mathematical relationships that hold true during the scaling process. They see how this can be useful in real-world situations like when engineers design wearable or implantable biosensors. This prepares students for the associated activity in which they use this knowledge to help them reduce or enlarge their drawings as part of the process of designing their own wearables products. Pre/post-activity quizzes, a worksheet and wrap-up concepts handout are provided.
This word problem may be used for instructional or assessment purposes, depending on where students are in their understanding of addition and how the teacher supports them.
This 5th grade unit iterates an earlier version and is designed to maximize the integration of science with the other content areas, especially English Language Arts and Math. It is designed so it can be used with in-person or remotely and includes learning activities that can be delivered via Zoom or another similar platform, as well as activities students can complete in-class, independently, or with their families. You are free to adapt this OER unit as needed. Please note that this unit is a first draft beta version, so please communicate any questions, errors or omissions, feedback and suggestions for improvement to kimberley.astle@k12.wa.us.
The purpose of this task is to help students see that 4_(9+2) is four times as big as (9+2). Though this task may seem very simple, it provides students and teachers with a very useful visual for interpreting an expression without evaluating it.

This short video and interactive assessment activity is designed to teach fourth graders about selecting the incorrect statement.
This short video and interactive assessment activity is designed to teach fourth graders about selecting the numbers from a given set.
Students gain experience and practice with three types of word problems using the "Take From" context: result unknown, change unknown, and start unknown.
This short video and interactive assessment activity is designed to teach third graders about shortening multiplication expressions (associative property).
