Pre-K-2

The activities in this four-part ladybug cluster presents a rich computer environment in which students can use their knowledge of number, measurement, and geometry to solve interesting problems. Planning and visualizing, estimating and measuring, and testing and revising are components of the ladybug activities. These activities can help students build ideas about navigation and location, as described in the Geometry Standard, and use these ideas to solve problems.

• Part 1Designing a Virtual Path, students create a path that enables the ladybug to hide under a leaf.
• Part 2Making Triangles, students will use 45- and 90-degree angles to create triangles and design paths for the ladybug.
• Part 3Making Rectangles, students plan the steps necessary for the ladybug to draw rectangles of different sizes.
• Part 4Ladybug Mazes, students plan a series of moves that will take the ladybug through a maze.

### 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.

### Making Triangles

Pre-K-2
In this activity, students use 45- and 90-degree angles to create triangles, and develop an understanding of the relationship between angles and the shape of triangle. Students use their knowledge of number, measurement and geometry to design a "virtual path" using two different angles to help a ladybug reach its hiding place under a leaf.

### Making Rectangles

Pre-K-2
In this activity, students use their knowledge of number, measurement and geometry to plan the steps necessary for a ladybug to draw rectangles of different sizes. As they experiment, students begin to understand the relationship between the shape of a rectangle and the lengths of its sides. They also develop a sense of the amount of turn in a right angle.
