When modeling the pattern with tiles, you do not need to start over again to show each growth stage — just continue building the previous stage. This is a repeating and growing pattern that can be made by squaring the odd numbers and repeating each term twice. Children might look at the overall pattern as the number of tiles increases. Encourage children to find the difference between the totals in order to discover the number of tiles added each time.

When recording the differences, they may also notice that the pattern increases by multiples of 4 4 is added first, then 8, then 12 then 16, and so on. There are 49 blue tiles and 36 black tiles for a total of 85 tiles. Some students may notice that there are 7 blue tiles along one edge and that this is the 7th stage, for a total of 7 X 7 or 49 blue tiles. Some kids may need to use algebra calculator to help them discover patterns such as the difference or sum of different colors of tiles.

Some students may complete the growth sequence but not identify the pattern of colored tiles. They would benefit from deconstructing the pattern and assembling the tiles into arrays. Extension to this activity can be to ask kids to use the rule they have discovered to find out the number of tiles in stage 20 without having to extend the chart or using the manipulatives. Solving this new problem will help to deepen their understanding of the pattern. A variation on the design growth pattern activity is to provide kids with tiles of a third color and ask them to add tiles in this color to the existing weave patterns to create squares.

Ask them to model the first three stages, just as they did in the original design growth activity.

They should record their results in a table and then look for patterns and develop algebra rules for sequences. Algebra worksheets asking exploratory questions or plotting graphs for all stages of each color can be provided along with this learning activity to provide more algebra practice problems to kids. In this learning activity, kids explore the concept of equality and variables. In the context of a literature connection, students use symbols and letters to represent the masses of different animals and to investigate relationships and express them algebraically.

Students identify relationships between the masses of the animals and write math equations that represent balanced tug-of-war teams. Solving algebraic equations is also achieved through this activity.

## Algebra Math Games

Prior to this learning activity, children should have had some experience in using variables symbols or letters in algebraic expressions, and in modeling with concrete materials. Ask kids to brainstorm ways they could represent each animal without having to draw each animal. They may suggest using letters, shapes, or graphics. How many different ways can the animals combine on either side of the teeter totter to make the teeter totter balance if you have a fox, 4 turtles, and 6 squirrels?

Deeper learning can be achieved by doing pre algebra worksheets, algebra word problems, and most importantly by asking exploratory questions throughout the activity. Adding a squirrel S to both sides maintains the balance. Now rearrange the letters on each side of the equation, as follows:. Ask kids to consider whether the new algebra equations are true.
