Feet and Yards

Overview

In Lesson 4 of 18 in Math Explorers: Measure, Graph, Solve, students compare the size of a foot and a yard and choose the most sensible unit for measuring familiar objects and distances. Students build on prior work using measurement tools and describing length, then apply their understanding to real pictures and everyday examples.

Learning intentions

• Students will be able to choose feet or yards to measure an object or distance.
• Students will be able to compare the length of a foot and a yard.
• Students will be able to explain why a unit is appropriate for a particular measurement.
• Students will be able to use a measuring tool to measure length.

Success criteria

• I can choose feet for medium-sized objects.
• I can choose yards for very long distances.
• I can explain that a yard is longer than a foot.
• I can choose the best unit in at least 4 of 5 examples.

Curriculum links

• Measurement — select and use appropriate tools, including rulers and measuring tapes, to measure length.
• Measurement — measure an object with different-sized units and describe how the unit size affects the measurement.
• Measurement — use addition and subtraction in length situations with measurements given in the same units.
• Measurement and Data — represent whole numbers as lengths from 0 on a number line.

Lesson structure (30 minutes)

1. 0–4 min · Hook and learning intention. Open with the hook and learning intention slides showing a picture of a classroom table and a playground distance; ask, “Would we use the same unit to measure both?” Students turn and talk, then share a prediction. Introduce the statement: “I can choose feet or yards to measure something.”

2. 4–10 min · Explicit comparison. Display the foot-and-yard comparison slides. Teacher shows a 1-foot ruler and a 1-yard measuring tool, placing them together to make the difference in length visible, and explains that a yard is longer than a foot. Students repeat and act out the vocabulary: foot, feet, yard, unit, and measure. Model measuring from one endpoint without gaps or overlaps.

3. 10–16 min · Move and measure. Teacher gives each student a turn to step off one foot and one yard with a partner, using the real unit models as a reference and reminding students to start at the same point. Students compare their steps and answer, “Which takes more space: one foot or one yard?” Revisit the movement and comparison prompt for the class discussion.

4. 16–21 min · Guided sorting. Show pictures of a shoe, table, hallway, and playground using the picture sorting slides. Teacher prompts students to select feet or yards and explain their reasoning. Students take turns dragging or placing color-coded feet and yard cards onto each picture, using “I choose ___ because ___.” Confirm that a shoe is generally better measured in inches, while a table may be measured in feet; a hallway or playground distance is better measured in yards.

5. 21–27 min · Independent practice. Distribute the five-example unit choice worksheet. Students select the best answer for five pictured or written examples and may point to a unit card before recording. Read each item aloud, pause for thinking time, and check answers individually. Students should complete the following choices: desk—feet; playground distance—yards; longer unit—yard; small eraser—inches; measuring tool—measuring tool.

6. 27–30 min · Review and exit check. Return to the review and exit prompt and ask each student to complete the sentence, “I choose ___ when ___.” Students show a feet or yards card for two final oral examples and explain one choice. Collect the worksheet as the lesson assessment and briefly celebrate accurate reasoning.

Resources

• the measurement comparison and sorting deck
• the five-example unit choice worksheet
• 1-foot ruler or physical foot-long model
• 1-yard measuring stick, yardstick, or measuring tape
• Feet and yard picture cards
• Large-print feet and yards choice cards
• Classroom objects and open floor space
• Colored markers or crayons

Assessment

• During modeling and sorting, listen for students who recognize that a yard is longer than a foot and who can connect the unit to the size of the object or distance.
• Use oral questioning and choice cards to check understanding: “Would you measure this in feet or yards? Why?” Record whether each student explains an appropriate choice.
• Use the five-item worksheet as an exit assessment. Students meet the target when they choose correctly in at least 4 of 5 examples.

Differentiation

• Support: Provide real foot and yard models, allow students to step off each unit, repeat answer choices, and offer two-choice cards rather than requiring students to recall the units independently.
• Dyslexia-friendly access: Use large print, uncluttered pictures, high-contrast color coding, and consistent icons for feet and yards. Read all directions and questions aloud, allow spoken answers, and avoid requiring students to copy vocabulary.
• Language support: Use sentence frames such as “I choose ___ because it is a ___ distance” and demonstrate each word with an action or object. Pair each vocabulary word with its visual unit icon.
• Extension within the task: Ask a confident student to explain why a yard is useful for a playground distance and to suggest another classroom object that could be measured in feet.
