Step-by-Step Guided Lesson
Step 1: Start Video
(Tips: Interact with the video by pausing, to ask questions or discuss information viewed with student.)
Step 2: Teach Lesson
Watch the video is Step 1. Once the video is finished, ask the student what would they use to measure a whale. View Solution
Demonstrate how to measure the length of something in the room using non-standard measurement units. Ask what is measurement
and bring out definitions to post on wall. Maybe ask what careers do you think have to use measuring (chef, scientist, architect,
construction, etc) to introduce the word wall.
The teacher will introduce items that need to be measured using non-standard items (inchworms, blocks, bears, paperclips, etc). The
student will make estimates and measure different items around the room using different nonstandard units of measurement; the
student will write about their findings.
Ask the student what did you learn today? What did you like about today’s activity?

Step 3: Complete the worksheet attached below.

Step 4: Review. Start the next lesson with the game or activity attached below for review so the student can demonstrate
understanding of this lesson before moving forward.
Measure It Outside! (Offline) activity
Take the student outside and find different items to measure such as leaves, rocks, etc. and use non-standard measurement units to
complete the task. Have the student write down their results.
