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.
3-5
In this lesson, students use fraction bars to explore
how to compare sizes of fractions. They conclude with an online Calculation
Nation
® game
called Fraction Feud.
3-5, 6-8
Students discover the
relationships between area and perimeter as they prep for playing Square Off, a
wonderful Calculation Nation
®
game. This lesson helps students understand the math of area and perimeter, which
will help to maximize their scores when playing the game. Creating human-sized
rectangles and working with geoboards provide concrete experiences before
moving on to pictorial and abstract work with area and perimeter of rectangles.
3-5
This hands-on lesson uses the book,
A Remainder of One, by Elinor J. Pinczes, to introduce division with remainder. Students will enjoy the story context as they explore different remainder situations and model division with arrays.
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.
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.
