Pre-K-2, 3-5
Use this tool to design a pattern using geometric shapes.
Pre-K-2, 3-5, 6-8
This tool allows you to create any geometric shape
imaginable. Squares, triangles, rhombi, trapezoids and hexagons can be created,
colored, enlarged, shrunk, rotated, reflected, sliced, and glued together.
Pre-K-2, 3-5
This kinesthetic lesson involves using models to practice
regrouping and to reinforce place value understanding. Students work together
to play games involving bases 10 and 5. Students will also interpret models as
numbers.
Pre-K-2, 3-5
In this lesson, students learn to compose and decompose
numbers into the hundreds place as they move from standard form to expanded form and back again.
Students explore composing and decomposing numbers using base ten blocks and
place value cards.
3-5
In this lesson students create rectangular arrays to
represent sizes of chocolate boxes. They find all of the factors of each number
up to 36 and learn the difference between prime and composite numbers. Then
they play an online game to practice finding factors for each product up to 36.
Pre-K-2
In this lesson,
students use base ten blocks to construct two- and three-digit numbers on a
place value board. They then play a game using base ten blocks to model numbers
up to 100.
Pre-K-2
Students
use coin blocks, a
concrete representation of coins, to compose and decompose numbers by counting
money. They also use an interactive tool to practice the same skills
pictorially.
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.
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
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.
