6-8
In this lesson, students investigate relationships between numbers, identify number patterns,
represent the information in graphic chart form, and generalize the results of an investigation. Specifically, students explore the relationship between a whale's length and its weight.
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.
Pre-K-2
In this lesson for grades 1‑2, students balance pairs of like and
unlike objects by changing distance from the fulcrum. Students use a
crayon (as the fulcrum) and a ruler to represent the balance.
3-5
In this lesson for grades 3‑5, students participate in activities in
which they focus on patterns and relations that can be developed from
the exploration of balance, mass, length of the mass arm, and the
position of the fulcrum. The focus of this lesson is determining the
position necessary to balance uneven objects and the effect on balance
of moving the fulcrum.
6-8
In this lesson for grades 6‑8, students participate in activities in
which they focus on patterns and relations that can be developed from
the exploration of balance, mass, length of the mass arm, and the
position of the fulcrum. The focus of this lesson is the relationship
between the length of the arm and the mass of the objects.
Pre-K-2
In this lesson, students participate in activities to develop concepts of measurement and statistics. Students are asked to measure distances using non-standard units and to record their measurement in a bar graph. Then they are asked to make comparisons using the bar graph.
6-8
Using the story "The Celebrated Jumping Frog of Calveras County" by Mark Twain, students simulate a jumping-frog contest and determine the distances "jumped." The students record the distance of individual jumps in centimeters and determine the total distance jumped (the sum of the three separate jumps) and the official distance (the straight-line distance from the starting line to the end of the frog's third jump). The students compare the range and median of the total distances with those of the official distances of the group.
6-8
Students measure distances using standard and nonstandard units and
record their measurement in various tables. Then they are asked to use
descriptive statistics to report the results. During a top-spinning
contest, students measure the distance along a curve using indirect
measurement. They record the data for their group in a chart, and
compute their individual median and the group median.
Pre-K-2
The following lesson introduces elementary students to subtraction. The
objective is to create a link between students' experiences and
mathematics. By the end of the lesson it is expected that students have
a deep understanding of subtraction and how it relates to their world.
This lesson was adapted from "Helping Students Understand Subtraction"
by Anita Page, which appeared in the November 1994
Teaching Children Mathematics, Vol. 1, No. 3.
