Sketch Up
Learners estimate and measure exact. In this geometry lesson, students create different object in three-dimensional pattern. They use SketchUp to create their shape and perform measurements on their shapes.
Curated OER
All About Ratios
Students investigate the use of multiplication and division of whole numbers to solve problems including equivalent ratios and rates.
Curated OER
A Relatively Far Out Idea: Estimating
Students investigate methods of estimating through cooperative group activities, hands-on activities, the use of tables and graphs and an interactive video.
Curated OER
Thermometers Rising
Third graders read a Fahrenheit thermometer from an actual thermometer. In groups, they are provided with ink pads and a thermometer stamp. They use the stamps on plain white paper and use red pencil to take the temperature readings.
