Estimating and Rounding-Pretest Questions
In this estimating and rounding worksheet, students complete a set of 10 multiple choice questions. Students may click on a link for answers or to print page.
Curated OER
Powers of 10
Students explore universe, and examine how big it really is and how scientists measure the distances or sizes of things by estimating sizes of different objects and reading and writing numbers in scientific notations.
Curated OER
Locating the Salt Front
Learners use Hudson River salinity data to create a line
graph that shows the location of the salt front, and use math
skills to explore how this location varies over time. They use the graph to estimate the location of the salt front...
Curated OER
Paper Capers
Students demonstrate how much paper is thrown away in their classroom in one week. They estimate the weight of paper used, weigh the paper at the end of five days, and discuss how students can use less paper.
Curated OER
Buying My First Car
Students pretend they are about to buy their first new car. They must do all the calculations necessary to estimate the cost of purchasing the car. They see that the math they learn in school really does have real-life applications.
