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.
Pre-K-2
In this activity, students use 45- and 90-degree angles to create triangles, and develop an understanding of the relationship between angles and the shape of triangle. Students use their knowledge of number, measurement and geometry to design a "virtual path" using two different angles to help a ladybug reach its hiding place under a leaf.
Pre-K-2
In this lesson, students use virtual manipulatives to explore triangles. They create virtual representations of triangles on an electronic geoboard. They also identify shapes within shapes using tangrams. This activity is appropriate for a computer lab, so all students have access to the virtual manipulatives.
Pre-K-2
Students classify buttons and make disjoint and overlapping Venn diagrams. In an extension, they make and record linear patterns.
Pre-K-2
Students use the knowledge and skills gained from previous lesson by placing yarn strips appropriately on 4' × 3' strips of paper and drawing around them to create a map of their body. Then the students use directional and positional words to describe their body map.
Pre-K-2
This activity provides opportunities for creative problem solving while
encouraging young students to estimate length and angle measure. Using
the Turtle Pond Applet,
students enter a sequence of commands to help the turtle get to the
pond. Children can write their own solutions using LOGO commands and
input them into
the computer. The turtle will then move and leave a trail or path
according to the instructions given.
Pre-K-2
Everyone loves a good card trick, and this lesson allows
young students to learn a fun and impressive trick while simultaneously
practicing and mastering the all-important combinations of ten. In this trick
one student is a “mathemagician.” He presents a deck of cards to his classmate,
who removes three cards from the deck. After some fancy card work, the
identities of the three cards are “magically” determined to everyone’s
amazement.
Pre-K-2, 3-5, 6-8
Participate in activities to analyze information represented
graphically.
Pre-K-2, 3-5, 6-8
Focus
on patterns and relations
that can be developed from the exploration of balance, mass, length of
the mass arm, and the position of the fulcrum.
Pre-K-2
Build ideas about navigation and location, as described in the
Geometry Standard, and use these ideas to solve problems.
