Designing a Virtual Path

Pre-K-2
In this activity, students use their knowledge of number, measurement and geometry to design a "virtual path" which enables a ladybug to hide under a leaf. They also develop navigational skills by testing to see if their path is accurate and revising their solutions.

Ladybug Mazes

Pre-K-2
In this activity, students plan a series of moves that will navigate a ladybug through a maze. Their plans turn the ladybug at the appropriate corners and keep it on a path without crossing the walls. This activity helps students gain experience in estimating length and angle measures.

National Population Projections

3-5
In this activity, students examine the United States Census Bureau Web site to investigate population projections from 1990-2100. Using the five provided pyramids, students analyze the data to determine
how the population is distributed over time, and explain what factors might contribute to these trends.

State Population Projections

3-5
In this activity, students  examine the United States Census Bureau Web site to investigate projections of the total population of states from 1995-2025. Using the provided data, students will analyze statistics from five states of their choice, develop specific research questions using the data, and create three graphs to compare and contrast the
information.

How Many Left?

Pre-K-2
This lesson encourages the students to explore the familiar set model of subtraction. The students write story problems and find differences using sets, including subtracting all and subtracting zero. They record the differences in a chart.

Where Will I Land?

Pre-K-2
In this lesson, the students find differences using the number line, a continuous model for subtraction. [Number can be considered in two ways: discrete and continuous. The counting and set models use the discrete form of number.] Students are encouraged to predict differences and to compose puzzles involving subtraction.

What Balances?

Pre-K-2
This lesson encourages students to explore another meaning of subtraction, the balance. They use subtraction facts to generate related addition facts and explore at the concrete level the idea of subtraction as the inverse of addition.

Measurement

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.
