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.
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
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.
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.
3-5, 6-8
In this activity for grades 4-6, students attempt to identify the concept of a million by working with smaller numerical units, such as blocks of 10 or 100, and then expanding the idea by multiplication or repeated addition until a million is reached. Additionally, they use critical thinking to analyze situations and to identify mathematical patterns that will enable them to develop the concept of very large numbers.
3-5, 6-8
This lesson provides students an opportunity to assess their understanding of mathematical vocabulary as they relate to key concepts from the five content areas. Through the use of a familiar game format, Bingo, students will identify numbers 0‑75 that correspond to mathematical descriptions from math vocabulary clue cards.
3-5
This lesson focuses on forming 3-digit address numbers to meet specific requirements. Careful reading of information and understanding of mathematical language are important to finding appropriate solutions. Using the problem-solving strategies of looking for patterns and establishing an organized list will aid students in finding all the possible solution sets.
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.

Exercise your factoring ability against a human or the computer in this Calculation Nation game.
3-5, 6-8
This applet allows students to individually practice working with relationships among fractions and ways of combining fractions.
