These word problems address common errors that students make when adding fractions.
Students gain an understanding of the factors that affect wind turbine operation. Following the steps of the engineering design process, engineering teams use simple materials (cardboard and wooden dowels) to build and test their own turbine blade prototypes with the objective of maximizing electrical power output for a hypothetical situation—helping scientists power their electrical devices while doing research on a remote island. Teams explore how blade size, shape, weight and rotation interact to achieve maximal performance, and relate the power generated to energy consumed on a scale that is relevant to them in daily life. A PowerPoint® presentation, worksheet and post-activity test are provided.
Students will use dominos to learn about common denominators and fractions
This task engages students in thinking about number patterns.
This problem involves fraction multiplication that can be solved with pictures or number lines.
This short video and interactive assessment activity is designed to give fifth graders an overview of speed based problems.
This short video and interactive assessment activity is designed to give fourth graders an overview of speed based problems.
One goal of this task is to help students develop comfort and ease with adding fractions with unlike denominators. Another goal is to help them develop fraction number sense by having students decompose fractions. Because the Egyptians represented fractions differently than we do, it can also help students understand that there can be many ways of representing the same number.

Students will be using real-life energy use data to learn how to use spreadsheets and create graphs to better organize and view data. Discussions can then follow to analyze the data and explain the usage. Real rates are then provided, and students can use the electricity consumed data to create a utility bill for the consumer and compare the standard Residential Service charges to if the member were instead billed by the “Time of Use” rate.
Students use a recipe to prepare a hydrogel gummy snack, which has a similar consistency to that found in a Haribo® gummy product. They must convert the juice and gelatin-based recipe from US customary units to metric units with dimensional analysis conversion. After unit conversion, teams are given different gelatin quantities and design their gummy snacks. Once the candies have solidified, student groups compare the gummy snacks are for viscosity and taste. After a taste test, teams reflect on their experiment and brainstorm ways to iterate a better gummy recipe.
This task helps students understand the meaning of the equal sign and to use it appropriately.
This short video and interactive assessment activity is designed to teach second graders an overview - equivalent decimals ending in zero.
