Pre-K-2
Students explore the use of variables as they solve for the weights of objects using information presented in pictures. They model situations that involve adding and subtracting whole numbers, using objects, pictures, and symbols.
Pre-K-2
In this activity, students choose a picture and use all seven tangram pieces to fill in the outline. They describe and visualize what figures look like when they are transformed through rotations, reflections, or translations, and are put together or taken apart in different ways. This activity helps students to develop their spatial memory and spatial visualization skills, to recognize and apply transformations, and to become more precise in their use of vocabulary about space. Students use an internet-based tool to explore tangram puzzles.
Pre-K-2
Students learn to pose mathematical questions about themselves and their surroundings through class. They gather data about eye color from their classmates and another class within their school. They organize this data to answer questions.
Pre-K-2
In this lesson, students work with data to complete an organized chart by doubling or halving numbers. Then, they compare data using vertical and horizontal bar graphs.
3-5
In this lesson, students complete a chart by adding or subtracting from a given value, use graphs to compare two categories of information, and identify number patterns.
Pre-K-2
This lesson emphasizes the connections between science and mathematics
by using a performance, or authentic, assessment format. Students have
the opportunity to explore applications involving their own heart. This
lesson was adapted from the article, "Ideas: The Beat of Your Heart,"
by Lisa M. Passarello and Francis (Skip) Fennell, which appeared in
The Arithmetic Teacher Vol.39, No.6 (February, 1992) pp. 32-39.
3-5
This activity involves taking a pulse, collecting and interpreting data, making predictions, and drawing conclusions. Its focus is the collection and analysis of data.
3-5
In this activity, students use the average adult's number of heartbeats per minute to predict how many times the heart would beat during various lengths of time. The students also draw conclusions on the basis of information about the human heart rate and that of other animals.
3-5
Students are encouraged to discover all of the possible combinations for outfits consisting of shirts and shorts. Students apply problem-solving skills (including elimination and collection of organized data) to draw their conclusions.
This lesson plan is also available in Spanish.
3-5
Students are encouraged to discover all the combinations for ice cream cones. They use problem-solving skills (including elimination and collection of organized data) to draw their conclusions. Students also discuss whether or not order matters mathematically for the given problem.
