Pre-Assessment Quiz – A short multiple-choice or hands-on assessment to gauge students' familiarity with rulers, units of measurement, and basic graphing.

Class Discussion & Brainstorming – Ask students, “What do you know about measuring?” and “When have you used measurement before?”

K-W-L Chart – Students list what they Know, Want to Learn, and later, what they Learned about measurement.

Hands-on Exploration – Provide students with rulers and ask them to measure random objects. Observe their techniques to identify misconceptions.

Exit Tickets – After each lesson, students answer a quick question such as, “Estimate and measure your pencil. Were you close?”

Observation & Anecdotal Notes – During hands-on measuring activities, take notes on student accuracy and use of tools.

Think-Pair-Share – Students work with a partner to compare measurements and discuss their strategies.

Whiteboard Checks – Students solve short measurement problems on whiteboards and hold them up for quick teacher feedback.

Mini Quizzes – Short quizzes every few lessons to check understanding of key concepts like estimating, measuring, and solving word problems.

Hands-on Measurement Project – Students measure real classroom objects and record their findings in a chart.

Graphing Activity – Students collect their own data (e.g., measuring classmates’ heights) and create a bar graph.

Word Problem Quiz – A mix of multiple-choice and short-answer problems requiring students to solve measurement-based math problems.

Performance-Based Task – Students apply their skills to a real-world scenario (e.g., "Measure your desk and find another object of similar length").

Self & Peer Assessment – Students complete a checklist on their confidence with measuring and review a peer’s measurement project for accuracy.
