### Measuring with Teacher’s Feet

Pre-K-2

In this lesson, students use nonstandard units to measure the distance between objects found in their classroom. They create a nonstandard unit by using an outline of the teacher’s foot and cutting around it to use as a “measurer.” Students generate a list of four or five objects in the classroom from which they will measure the distance to their work space.### Measuring with Our Foot

Pre-K-2

Students measure the same distances as in the previous lesson using an outline cutout of their own foot. This enables students to practice using nonstandard units and to compare the measurement totals using their feet and the teacher’s foot.### Learning to Measure with Ladybug

Pre-K-2

The mathematical foci of this lesson are geometric concepts, location, navigation, direction, and spatial relationships and measurement concepts, using nonstandard units to measure a distance, and the iteration of units, measurement by using the same unit of measure repeatedly to determine the total. Students practice measuring with multiple units and a single unit following the methods modeled by the teacher and those appropriate for their level of understanding.### Helping Ladybug Hide with Arrows and Angles

Pre-K-2

In this lesson, students use an applet (technology tool) to hide a
ladybug under a leaf. This requires experimentation, planning, and
understanding of spatial relationships and visual memory. ### Handy Map

Pre-K-2

This lesson engages students in creating a map of their hands. It provides purpose for using directional or positional words with mapping. The teacher draws a map of his or her hands and begins mapping them using words the students suggest. This allows the teacher to assess positional concepts students currently know and to build on that knowledge. Students create a simple map.### Ladybug Lengths

Pre-K-2

This lesson captures students’ interests, provides an introduction to and practice with the measurable attributes of length, and assesses student knowledge. This experience focuses student’s attention on the attributes of length and gives students the opportunity to develop knowledge of and skills in using nonstandard units of measurement.

The lesson begins with a connection to children's literature. As students practice measuring length, the do so using nonstandard units.

### The Length of My Feet

Pre-K-2

This lesson focuses students’ attention on the attributes of length and develops their knowledge of and skill in using nonstandard units of measurement. It provides practice with and remediation of the measurable attributes of length.### The Area of Things ...

Pre-K-2

Students have opportunities to recognize and use the attributes of length and area using non-standard units. ### Grouchy Lessons of Time

Pre-K-2

This lesson provides an introduction to and practice with the concept of time. The activities focus students’ attention on the attributes of time and enables students at varying levels to develop knowledge and skills in using time. ### Drop by Drop

Pre-K-2

In this lesson, students recognize and use the attributes of volume. They engage in activities that promote understanding of how to measure volume using standard units.
