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.
6-8
This lesson explores the
concept
of slope through a student-centered problem of data collection and evaluation.
Students guess which of several flights of stairs is steepest, and then use
measures of slope to test their hypothesis.
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.
9-12
This lesson allows students to explore the idea that
rainforest deforestation is occurring at an exponential rate. Students will use
provided research about Amazon deforestation and conduct their own research to
determine whether deforestation is occurring exponentially.
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.
6-8
Photographs, blueprints, models, and computer renderings may
serve as virtual representations of real cities. But how accurately do they
represent their real counterparts? In this lesson, students examine a computer
representation of a city and compare the sizes of its features with the sizes
of analogous features in a real city.
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.
6-8
Students use their class schedules to create
time-distance graphs by counting the number of walking strides they take from
their lockers and timing themselves as they walk through their class schedules.
They will use their graphs to answer questions about slope,
x- and
y-intercepts, and the meaning of horizontal and vertical lines.
