Number Subsets: Winning the Number Game
Eighth graders review their understanding about numbers and number systems through playing the Number Game. They create a list of numbers and based upon the characteristics and properties of the numbers they will earn points.
Curated OER
Commutative Property
First graders investigate the Commutative Property of Addition. It is introduced using models such as students, counters, balances and dominoes. They discover the order of the numbers in an addition sentence does not change the result...
Curated OER
Direct and Inverse Variation
Eighth graders participate in two data collection activities that involve direct and inverse variation. In the pre-assessment, 8th graders categorize numerical, graphical, and verbal representations as linear or nonlinear and determine...
Curated OER
Graphs Galore
Fourth graders conduct surveys to collect data. They analyze and interpret the data, then determine which type of graph is appropriate for the data. Students use the data to make predictions, discover patterns and draw conclusions...

Multiplication: Building Models, Representations and Explanations
First graders explore multiplication concepts through skip counting, repeated addition and arrays. Using animal characteristics as a context, 1st graders solve problems using mathematical tools such as hundreds charts, number lines, ...
Curated OER
Describing Patterns
Fourth graders investigate repeating and growing patterns. Models, graphs and words are used to describe, extend and represent patterns. Students use evidence from models and graphs to support the identification of patterns.
Curated OER
Buying and Financing the Car of Your Dreams
Eighth graders go to one of a number of web sites (provided by the teacher in a hotlist) to find a car they would like to buy if they were old enough. They would then be provided with the necessary information to compute monthly payments...

Exploring Function Graphs
Tenth graders investigate three different sets of data that relate temperature to another variable in the physical world. These illustrate linear, inverse and exponential relationships.
Curated OER
Models for Dividing Fractions
Sixth graders represent division of fractions using manipulatives, such as freezer pops, candy bars, and models such as drawings squares. They develop an algorithm from these examples and solve problems using fractions.
Curated OER
Fraction Models
Third graders make models of fractions and mixed numbers. Using fraction strips and drawing pictures, 3rd graders develop conceptual understanding of the equivalent forms. Students use the number line to represent and compare...
Curated OER
Drawing Lines of Symmetry
Third graders explore the concept of symmetry using geometric shapes, capital letters and various other shapes. They fold shapes to show symmetry, draw lines of symmetry and create symmetrical designs.
Curated OER
Customary Measurement Conversions
Fifth graders discover in hands-on activities the relationships between the measures. They work in groups to create conversion tables using familiar measuring tools. Students solve problems requiring conversions.
Curated OER
Choosing the Best Graph
Eighth graders produce and examine two sets of data and create what they believe to be the most appropriate graphs to represent these sets of data. After completing the pre-assessment, they discuss reasons for using each type of graph...
