| LESSON | SESSIONS | DESCRIPTION | SUPPLIES |
|---|---|---|---|
LESSON 1Group and |
2–3 | Students group and count objects by ones, twos, fives, and tens. They trade pennies for nickels and nickels for dimes to find the total amount of money efficiently and organize and efficiently count links in chains to prepare for measurement activities. |
|
LESSON 2Measure with |
1–2 | Students skip count by fives using chains of connecting links to measure and record the lengths of various objects. |
|
LESSON 3Rolling Along |
3–4 | The Adventure Book story, "Betty Builds a Better Racer" sets the context for a laboratory investigation in which students use nonstandard units to measure the length a toy car rolls. Students group and count by fives and tens while they collect, record, and analyze data, and are introduced to the concept of "fairness" by keeping certain experimental variables constant. |
|
LESSON 4Measure with |
3 | Students examine the relationship between the size of a unit and the number of units in a measurement. They measure, compare, and order the length of an object using different nonstandard units of measure while practicing good measurement techniques. |
|
LESSON 5Measure with |
1–2 | Students transition from measuring with nonstandard units to measuring in inches. They use 12-inch rulers to measure objects in the classroom. |
|
LESSON 6How Long |
2 | Students identify actions or activities that can be completed in a few seconds, about a minute, about five minutes, about an hour, or more than an hour. |
