Students will be able to measure and estimate lengths using inches and feet.
The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.
Explain to the students that today they will be measuring objects in the classroom.
Hold up a ruler and ask students, "What is this?" Allow students a minute to think-pair-share their answers.
Clarify that the object is a ruler and it is used to measure objects in inches, a unit of measurement equal to 2.54 cm or about the diameter of a quarter, and feet, a unit of measurement equal to 12 inches or about the height of a folder.
Tell the students that sometimes, instead of using a ruler to measure objects, they can estimate instead.
Give students two sticky notes labeled "inches" and "feet." Have students place the sticky notes on one object in the classroom they could measure using inches and another object in the classroom they could measure using feet.
