Measuring Angles
Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...
Curated OER
Estimation Zone
Students explore estimation. They estimate distance, weight, temperature and elapsed time. Students record their estimates and justify their estimations wtih a written response. After estimating, students take the actual measurements of...
Curated OER
Perimeter
Students use their hands, feet, computer, and rulers to measure the perimeter of objects. In this measurement lesson plan, students measure objects around the room and computer generated shapes.
Curated OER
Tower Power
Learners explore basic building and engineering concepts by constructing a structure that supports weight. They demonstrate an understanding of basic business concepts by estimating the cost and value of a building.
Curated OER
Practice With Decimals
In this decimal worksheet, learners solve decimal problems, estimating, balancing a checkbook, and finding the cost of a car using a given chart.
Curated OER
Junk Mail Overload!
Students discuss the "junk mail nuisance" with the teacher and share their opinions on the problem. Students collect a week's worth of junk mail, bring to class and complete a chart about the amount and weight. Students then complete an...
Curated OER
How Hot Is It?
Fourth graders practice estimating temperatures. They practice in Celsius and Fahrenheit.
Curated OER
Triangle Explorer
Students compute the area of triangles in a computer program. In this measurement lesson plan, students complete 5 easy, 5 medium, and 5 hard problems.
Curated OER
LEGO Balance
Students design and build a balance using LEGO, string, and a set of standard metric weights.
