In this quiz we explore various sequences, which not only make for fun puzzles but are central to algebra.
Could you describe this pattern well enough that someone could reproduce it without having seen it?
How many squares will be in Step
Does column have more stars or squares?
Hint: notice that each horizontal row has its own pattern.
In each figure, squares are either empty or filled with a circle. How many empty squares does Figure have?
has one unit cube and has additional unit cubes. Assuming the pattern continues as shown, how many unit cubes will have?
Note: You can play with the orientation of the blocks.
Extending patterns as we've done in the preceding questions is a foundational algebra skill.
While we can solve many problems like these in a straightforward manner, the use of variables, equations, and algebraic concepts unlocks a variety of additional problems.
Jill is arranging tables for a party that will be placed in one long row, end to end. Each side of each table can seat one person.
Which table shape cannot seat exactly people, regardless of the number of tables used?
