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, 9-12
This lesson invites students to investigate the patterns when a "plus sign" (a cross-shaped arrangement of five squares) is placed on the board in various locations. Students will conjecture about the pattern of the five displayed numbers, the sum of the five numbers, and any other patterns that they notice. Students may also explore similar patterns when other shapes, such as a 2 × 1 rectangle, are placed on the hundreds board.

Use this activity to practice solving systems of equations. Use this tool to check students' answers.
3-5
The activities use The Three Little Pigs (Galdone 1970) and Cinderella (Grimm
and Grimm 1981) to motivate students to think and reason
mathematically.
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.
6-8
Create
a shape sorter and consider all possible moves that will return a shape to its
original position.6-8, 9-12
In this unit, students will investigate a relationship
between recursive functions and exponential functions.
6-8
Use
a pan balance to study equality, order of operations, numerical and variable
expressions, and other key algebraic concepts.3-5
Focus
on connections between mathematics and environmental concerns. 6-8, 9-12
Use
movement to reinforce the concepts of linear functions and systems of
equations.
