The purpose of this task is for students to relate addition and subtraction problems to money and to situations and goals related to saving money.
This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.
The goal of this task is to show that when the whole is not specified, which fraction is being represented is left ambiguous.
This short video and interactive assessment activity is designed to teach third graders about number riddles (numbers up to 100,000).
Students learn the connection between the counting sequence and experience from their daily lives in this daily activity. It also helps give students a sense of how "many" each number is.
Students will breed fruit flies through several generations and record their data using mathematical models in order to demonstrate the inheritance of trait variations.
Students will have the opportunity to work in groups and investigate the effects of an “oil spill” in a water body. In a simulated “ocean” (a pan of water), students will drop a small amount of oil into the water and see the effects and interaction. In an introduction to the workshop, students discuss sources of pollution and oil contamination in water bodies – from point sources (tanker spills) and non-point sources (vehicle run-off). A brief discussion on preventing and cleaning up oil contamination will lead into the activity, in which the students will use a variety of materials to see what method works best for recovering the most oil from the water. Students will develop a proposal explaining which materials and procedures work best for cleaning up an oil spill. Students will also create a presentation to share their proposal.
This short video and interactive assessment activity is designed to teach fourth graders about one-step conversions between multiples of 10.
This short video and interactive assessment activity is designed to teach third graders about one-step conversions involving multiples of ten.
This task acts as a bridge between understanding place value and using strategies based on place value for addition and subtraction.
This short video and interactive assessment activity is designed to teach fourth graders about arranging numbers in specific orders.
In this ordering task each number has at most 3 digits so that students have the opportunity to think about how digit placement affects the size of the number.
In this task students must place 4-digit numbers into order from smallest to greatest and greatest to smallest.
