From baking to true science, being able to convert measurements is a necessity. In this lesson the students will learn to convert measurements using equivalent fractions and ratios.Being able to convert or change between the systems is very important for discussions between scientists and mathematicians!
Sample Classroom Procedure / Teacher Instruction
- Begin by explaining to students that there are different systems to measure mass, volume, and distance. Being able to convert or change between the systems is very important for discussions between scientists and mathematicians!
- While reading the content pages, reinforce vocabulary and give students additional examples of converting measurements with ratios problems in order to help them practice the new algorithm. Use the additional resources to enhance understanding.
- Introduce the notes on ratios for converting measurements. Have students practice problems between and within measurement systems. Use the additional resources to enhance understanding.
- Have students practice problems using the notes as their conversion chart.
- Follow Activity page with students. Have students work individually to make their charts.
- Distribute Practice page. Check and review the students’ responses as a class.
- Distribute the Homework page. Have students share some of their people, recipes, and animals at the beginning of the next class and discuss how they converted the measurements.
- In closing, ask students to try to remember the different measurements used in each system without looking at their conversion chart.
- Allow for responses and discussion.
