From skyscrapers to ants, comparing sizes with your class can be endlessly fun! This lesson will help your students compare short and tall sizes.
Students will be able to differentiate between short and tall.
Introduction (5 minutes)
- Sing the Tall and Short action song to the tune of "Are You Sleeping" (Frère Jacques): This is tall. (Open hands as wide as possible vertically.) This is short (Place hand an inch apart.) Tall and short. (Open hands wide vertically; then, bring them close together, x2.) Hotels are tall. (Raise one hand high in the air.) Puppies are short. (Place hand low to the ground.) Tall and short. (Open hands wide vertically then bring them close together, x2.)
- Sing it by yourself first, and have your students sing along the second time.
Explicit Instruction/Teacher Modeling (20 minutes)
- Give the definition of short and tall. For example, short is when something is a small distance and tall is when something has a greater height.
- Display two items side by side, where one is tall and the other is short. For example, show a baseball and a baseball bat.
- Explain to them that the baseball bat is tall compared to the ball because it has a greater height.
- Explain that the ball is short compared to the bat because it only has a short distance.
- Give students these materials to hold and compare them.
- Call two students to the front of the class and ask which is tall and which is short.
- Correct students if they provide the incorrect answer.
- Choose several pairs of students with varying heights to compare.
Guided Practice/Interactive Modeling (15 minutes)
- Place students in pairs.
- Give students 10 to 15 blocks per pair.
- Instruct one person in the pair to build a tall tower and the other to make a short tower.
- Have students compare the sizes of the towers.
- Instruct pairs to switch roles building a tower of the opposite height.
Independent Working Time (15 minutes)
- Give students the Comparing Short and Tall worksheet.
- Read through the instructions for each section with the class.
- Enrichment: Direct your students to measure the height of the towers they build. Instruct them to use a ruler and state how tall or short they are.
- Support: Point around the room to give students examples of tall items and short items. Give your students extra assistance with the worksheet.
