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, 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.
3-5
In this lesson, students use pattern blocks to create
polygon "chains" and calculate the perimeter of the trains as they get
longer. The students will recognize and create patterns based on adding the
same shape repeatedly to the train. The students then write algebraic
expressions to describe the patterns.
3-5
In this lesson, students develop their understanding of the
terms
quadrilateral,
parallel, and
right angle. They apply that understanding in problem-solving
activities with tangrams.
3-5
Students learn to calculate elapsed time by using a
timeline, and then complete three engaging and fun activities that plan a
circus performance, their class schedule, and their day.
6-8
In Parts I and II of this investigation, students learn about the notion of equivalence in concrete and numerical settings. As students begin to use symbolic representations they use variables as place holders or unknowns. This part of the i-Math investigation illustrates the continued transition from the concrete balance view of equivalence to a more abstract view.
3-5, 6-8
Using inversions — words that can be read in more than one way — as the context, students will be introduced to various types of symmetry. After exploring the symmetries that exist with letters of the alphabet, they will make inversions of their own name.
Pre-K-2
In this activity, students use their knowledge of number, measurement and geometry to plan the steps necessary for a ladybug to draw rectangles of different sizes. As they experiment, students begin to understand the relationship between the shape of a rectangle and the lengths of its sides. They also develop a sense of the amount of turn in a right angle.
