### 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. ### The Weight of Things

Pre-K-2

This lesson introduces and provides practice with the measurable attributes of weight. It also gives an opportunity to assess student knowledge of and skill in using measurement of mass. This learning experience focuses students’ attention on the attributes of weight using hands-on activities and active learning. ### Two-Square Repeating Patterns

Pre-K-2

In this activity, students analyze how repeating patterns are generated. Using the interactive computer applet, students create, compare, and contrast pattern units of two squares and predict how patterns with different colors will appear when repeated in a grid and check their predictions.### Multiple-Square Repeating Patterns

Pre-K-2

In this activity, students create and analyze repeating patterns using
pattern units of three, four, and five squares. They predict how
patterns with different numbers of squares will appear when repeated in
a grid, and check their predictions. Students investigate similarities
and differences between the rows, columns, and diagonal patterns
created with each pattern unit.### Different Representations

Pre-K-2

In this activity, students create patterns using connecting cubes and
describe various patterns they find in different sequences of cubes.
Students explore and describe connecting patterns, and extend their
patterns using a sequence of sounds and shapes. Students investigate
various ways to interpret the same sequence of cubes by exploring ways
to describe patterns translating from one representation to another.### Repeating and Growing Patterns

Pre-K-2

In this activity, students create and explore more complex patterns
such as "growing patterns" which have related but different
relationships to "repeating patterns". Students form generalizations,
analyze, and describe growing patterns using connecting-cubes, and
explore what happens when growing patterns "double" or "split."
