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.
Pre-K-2
In this lesson, students use 2 colors of snapping cubes and
other manipulatives to model addend pairs for the number 10. They explore the
different addend pairs, and play a game to apply their understanding.
3-5
In this activity students will analyze data and select fictional
baseball players based on player statistics. They will apply concepts of
probability to choose the order of batters on their team. After creating a
spinner for each player to represent the statistics, they use the spinners to
play a simulated baseball game.
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.
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
In the book
Balancing Act by Ellen Stoll Walsh, two mice find a
teeter-totter and have a fun time balancing each other. When more animal
friends come along to join them, they find their teeter-totter unbalanced. This
hands-on lesson uses the book as an introduction to the concept that both sides
of an equation need to be equal and balanced in order to use the "equal to" symbol; otherwise the "not equal to" symbol must be used. In
addition, students use pictures and symbolic letters to represent variables in
an equation.
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.
