MATHEMATICS RESOURCES

Investigating Equivalent Fractions with Relationship Rods
This resource is a lesson plan, one of a multi-part unit from Illuminations, where students investigate the length model by working with relationship rods to find equivalent fractions. Students develop skills in reasoning and problem solving as they explain how two fractions are equivalent (the same length). Relationship rods are wooden or plastic rods in ten different colors, ranging in length from one to ten centimeters.


Base Ten Blocks
This is an interactive resource where students use base ten blocks to make the numbers shown on the screen.


What’s Poppin’?
This resource is a lesson plan in which students determine and compare weights and volumes of popped and unpopped corn to make predictions and solve problems.


Bubble Mania
This resource is a lesson plan where students are given opportunities to practice measurement skills as they examine a soap bubble print. Students follow a recipe to make a soap bubble solution. They use the soapy solution to blow large bubbles with a plastic drinking straw until they pop leaving behind a circular print. Students find the diameter, circumference, and area of the bubble print.


Growing, Growing, Gone
This resource is a unit plan which consists of several task involving linear and exponential models. This task in particular is a solidify understanding task for students to use their understanding of linear and exponential patterns of growth to model the growth of a population. Students are given two data points and asked to create both an exponential and a linear model containing the points. Students may draw upon their experience with arithmetic and geometric means to develop new points in the model. The task provides opportunities to create tables, equations, and graphs and use those representations to argue which model is the best fit for the data. The lesson begins on page 44.


Key Visualizations: Geometry
In this animation, students use transformations to show two triangles are similar. The resource also provides a teaching and question guide under the “About This Animation” heading. NOTE: You will need to click on the play button to see the animation. Choose one of the transformations and the animation will begin.


Exponential Stations - Comparing Graphs
In this online activity, students learn about the parts of exponential functions by graphing groups of graphs in different stations and identifying similarities and differences of the graphs. Teacher video is also provided to help guide the lesson.
