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.
9-12
In the third lesson, students identify a function that models the data. An interactive graphing tool can be used to determine a function that fits the data points.
3-5, 6-8
Using the online game Deep Sea Duel, students play a card game against Okta. The objective is to choose cards so that some subset of three cards within their hand has a particular sum. Students will play several variations of the game, attempt to identify a winning strategy, and compare the game to other games that they know.
6-8
The interactive paper pool game in this i-Math investigation provides an opportunity for students to further develop their understanding of ratio, proportion, and least common multiple.
6-8
In this lesson, students construct the 12 pentomino figures then utilize them to explore area and perimeter. By the end of the lesson students will be able to identify those constructions that are pentominoes and those that aren't. Students will also be able to calculate area and perimeter of pentomino combinations.
Pre-K-2, 3-5
This tool allows you to practice multiplying single-digit numbers.
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.
3-5, 6-8
Start with a number and find its factors. Then, start with factors and multiply to find the product.
