This task serves as a bridge between understanding place-value and using strategies based on place-value structure for addition.
This task presents students with some creative geometric ways to represent the fraction one half. The goal is both to appeal to students' visual intuition while also providing a hands on activity to decide whether or not two areas are equal.
Students practice rounding whole numbers with this task.
In this challenging instructional task students relate addition and subtraction problems to money and to situations and goals related to saving money.
Students explore concepts of perimeter and geometry, specifically measuring perimeter. They start by exploring the specific attribute of perimeter, and then come to differentiate between perimeter and area as different measurements.
Students explore the volume of three-dimensional shapes, connecting it to the operations of multiplication and addition, as well as classify two-dimensional shapes hierarchically.
Kids need multiple experiences to practice what they've learned. This lesson is one in a series about measuring and ordering objects.
This is a rectangle subdivision task; ideally instead of counting each square. students should break the letters into rectangles, multiply to find the areas, and add up the areas. However, students should not be discouraged from using individual counting to start if they are stuck. Often students will get tired of counting and devise the shortcut method themselves.
In this video segment from Cyberchase, the CyberSquad determines the fairness of a game in which there are three shapes distributed equally on nine squares.
Students practice counting forward or backward in this class activity.
Most bears are getting ready to hibernate this time of year. NOT IN MY ROOM! These little brown bears will be on the hunt for shapes they see.
These word problems about money require students to think in base 10.
Students see how different levels of surface tension affect water's ability to move. Teams "race" water droplets down tracks made of different materials, making measurements, collecting data, making calculations, graphing results and comparing to their predictions and the properties of each surface, determining which surface exhibits the highest (or lowest) level of surface tension with water. They apply their results to make engineering recommendations for real-world applications.
The purpose of this task is to help students understand composing and decomposing ones, tens, and hundreds. This task is meant to be used in an instructional setting and would only be appropriate to use if students actually have base-ten blocks on hand.
Students build their competencies in measurement, relating multiplication to the conversion of measurement units and exploring strategies for solving measurement problems.
This short video and interactive assessment activity is designed to teach fourth graders about using the four operations with money - word problems.
This short video and interactive assessment activity is designed to teach fourth graders about place value problems involving money.
This short video and interactive assessment activity is designed to teach fifth graders about multiplication and division with money.
Using manipulatives, students figure out patterns in problems involving seating arrangements. They write algebraic equations to describe the relationships.
Students are introduced to algebraic expressions that use more than one variable and have multiple solutions. They figure out combinations of two items at different costs, with each combination adding up to 100.
