Understand how numbers can represent relational rules, such as height comparisons and spatial grids (Supercells).
Hook on how numbers can represent relationships.
Numbers don't always mean a quantity! Sometimes they are codes. If a group of children stands in a line, they can use numbers to secretively describe who is taller than whom.
Explain the rules of the taller neighbor game.
Imagine standing in a line with your friends. You can use numbers as a secret code to describe the heights of the people standing right next to you!

Test understanding of the neighbor rule.
Can a child standing at the very end of the line ever accurately say '2' according to the taller neighbor rule?
Introduce the Supercell grid puzzle.
Numbers can also form patterns when placed in a 2D grid. We can look for special numbers called Supercells based on their placement.

Identify the supercell in a sequence.
In the number grid puzzle, certain numbers stand out based on their spatial relationships. A cell is marked as a if the number in it is larger than its cells. Let's look at a specific row of numbers: 43, 79, 75, 63. To find the special number, we must compare each value to its immediate left and right neighbors. Which number in this row is a supercell? The correct answer is . This is because is strictly than both 43 and 75. Practicing these grid comparisons is a great way to build computational thinking skills.
