Comparing the World

Explicit Instruction/Teacher Modeling

• Explain that there are all sorts of things you can measure in the world. Tell the class that they just measured which table had more pencils and which table had less.
• Say, “More and less are opposites, just like big and small. You can compare groups of objects to see if there are more or less objects in each group, just like you can compare objects to see if they are bigger or smaller.”
• Pick three objects in the classroom and bring them to the front of the class. Tell students that you are going to put the objects in order from smallest to biggest. Order the objects, talking through how you know which ones are bigger and which ones are smaller.

Guided Practice/Interactive Modeling

• Tell students to go get three objects in the classroom. Have them order the objects from smallest to biggest.
• Hand out pieces of paper and have students draw the objects that they found, again ordering them from smallest to biggest.

Independent Working Time

• Tell students that they are now going to practice solving real-world problems where they compare objects.
• Hand out the Measurement in the Kitchen and Measurement in the Garden worksheets. Have students complete the worksheets independently.

Enrichment: Have students write or verbally tell their own measurement word problems.

Support: Have students complete only half of the problems on the worksheet.

Assess students’ understanding by having them share their answers to a partner.

Call on students to share a real-world word problem about objects in the classroom. Work together as a class to solve the problem.
