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.
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.
Pre-K-2
In this lesson, students use virtual manipulatives to explore triangles. They create virtual representations of triangles on an electronic geoboard. They also identify shapes within shapes using tangrams. This activity is appropriate for a computer lab, so all students have access to the virtual manipulatives.
Pre-K-2
Students classify buttons and make disjoint and overlapping Venn diagrams. In an extension, they make and record linear patterns.
Pre-K-2
Students use the knowledge and skills gained from previous lesson by placing yarn strips appropriately on 4' × 3' strips of paper and drawing around them to create a map of their body. Then the students use directional and positional words to describe their body map.
9-12
In the third lesson, students identify a function that models the data. An interactive graphing tool can be used to determine a function that fits the data points.
6-8
The interactive paper pool game in this i-Math investigation provides an opportunity for students to further develop their understanding of ratio, proportion, and least common multiple.
6-8
In this lesson, students construct the 12 pentomino figures then utilize them to explore area and perimeter. By the end of the lesson students will be able to identify those constructions that are pentominoes and those that aren't. Students will also be able to calculate area and perimeter of pentomino combinations.
Pre-K-2, 3-5
This tool allows you to practice multiplying single-digit numbers.
Pre-K-2
This activity provides opportunities for creative problem solving while
encouraging young students to estimate length and angle measure. Using
the Turtle Pond Applet,
students enter a sequence of commands to help the turtle get to the
pond. Children can write their own solutions using LOGO commands and
input them into
the computer. The turtle will then move and leave a trail or path
according to the instructions given.
