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.
9-12
In this lesson, students will manipulate three paper circles
to explore four circle theorems. Using paper folding allows the lesson to be
more accessible to kinesthetic learners.
6-8, 9-12
In this lesson, students will develop an understanding of the Fibonacci Sequence (and its connection to Golden Rectangles), Golden Ratio, Golden Rectangle, and the term
ratio (as it applies to rectangles). Students will use tools and construction techniques to demonstrate geometry prowess and be able to observe the Golden Rectangle in nature and in the classroom.
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.
