3-5
Students will use
base ten blocks to model decimal multiplication. They will assign different
values to the different base ten blocks to explore the consistent relationship
between the types of blocks. They will also discover different factors for the
same product. These activities will help students develop a conceptual
understanding of decimal multiplication.
3-5
In this lesson, students are presented with a design
challenge: a company that produces egg cartons wants to create a package for 24
eggs. The company wants to know all of the possible ways to arrange 24 eggs
into rectangular packages. Students work together to find the arrays and
respond to the egg company.
3-5
Division
is one of the most difficult operations for students to master, in part,
because there are many steps to keep track of and students often do not
understand the mathematical reasoning behind each step. In this lesson,
students will apply the strategies behind division, and learn how those strategies
can be translated into mathematical steps.
3-5
In this lesson,
students use operations of whole numbers and/or fractions to determine the
precise numbers of three types of dried beans needed to make salads. The use of
manipulatives and partner activities provide differentiation and support
learning for students of varying abilities.
Pre-K-2, 3-5
In this lesson,
students will use operations to discover
patterns with integers in magic squares. They will apply what they have learned when building their own magic
squares.
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
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, 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.
