3-5
In this lesson, students explore the relationship
between perimeter and area. Students use pattern blocks to build polygons to
explore how the perimeter can be different for two or more polygons with the
same area.
Pre-K-2, 3-5
In this lesson, students
use a visual model using snap cubes or grid paper to build numbers in two
columns to show whether they are odd or even. They then use the models
to generalize about sums of odd and even numbers.
3-5
In this lesson, students use pattern blocks to create
polygon "chains" and calculate the perimeter of the trains as they get
longer. The students will recognize and create patterns based on adding the
same shape repeatedly to the train. The students then write algebraic
expressions to describe the patterns.
3-5
In this lesson, students develop their understanding of the
terms
quadrilateral,
parallel, and
right angle. They apply that understanding in problem-solving
activities with tangrams.
3-5
Students learn to calculate elapsed time by using a
timeline, and then complete three engaging and fun activities that plan a
circus performance, their class schedule, and their day.
3-5
Students are introduced to some of the basic polyhedra. Students explore the shapes of the faces of these solids.
3-5, 6-8
Using inversions — words that can be read in more than one way — as the context, students will be introduced to various types of symmetry. After exploring the symmetries that exist with letters of the alphabet, they will make inversions of their own name.
3-5, 6-8
In this activity for grades 4-6, students attempt to identify the concept of a million by working with smaller numerical units, such as blocks of 10 or 100, and then expanding the idea by multiplication or repeated addition until a million is reached. Additionally, they use critical thinking to analyze situations and to identify mathematical patterns that will enable them to develop the concept of very large numbers.
3-5, 6-8
This lesson provides students an opportunity to assess their understanding of mathematical vocabulary as they relate to key concepts from the five content areas. Through the use of a familiar game format, Bingo, students will identify numbers 0‑75 that correspond to mathematical descriptions from math vocabulary clue cards.
3-5
This lesson focuses on forming 3-digit address numbers to meet specific requirements. Careful reading of information and understanding of mathematical language are important to finding appropriate solutions. Using the problem-solving strategies of looking for patterns and establishing an organized list will aid students in finding all the possible solution sets.
