Toothpick Patterning and Explicit Rules

The video tutorial explains a patterning problem involving toothpicks and hexagons. The task is to determine the greatest figure number that can be constructed with 38 toothpicks. The teacher guides students through analyzing figures, identifying patterns, and creating an explicit pattern rule. The rule is tested with examples, and a concluding validation statement is made. The tutorial emphasizes understanding the problem, recognizing patterns, and applying mathematical rules to solve it.

What is the main objective of the patterning problem discussed in the video?

• To determine the number of toothpicks in a single hexagon

• To construct a hexagon with 38 toothpicks

• To find the smallest figure number with 38 toothpicks

How many toothpicks are used in the first figure?

• 8

• 6

• 5

• 7

What shape is constructed in the first figure?

• Triangle

• Square

• Hexagon

• Pentagon
