Generating Number Patterns and Rules

Miss Velli introduces a math lesson on generating number sequences using input-output tables and function machines. The lesson focuses on patterns with multiple rules, such as doubling numbers and adding one, or rotating shapes. Students learn to use T-charts and Double T-charts to organize and apply these rules effectively. The video provides examples and emphasizes the importance of applying all rules to each step in a sequence.

What is the main focus of this week's math lesson?

• Understanding algebraic expressions

• Exploring input and output tables

• Learning about geometric shapes

• Studying historical mathematicians

What should you remember when dealing with patterns that have more than one rule?

• Apply only the first rule

• Ignore the second rule

• Use a calculator

• Apply all given rules

What is the guiding question of the lesson?

• How to calculate the area of a circle?

• How to generate a number sequence with two or more rules?

• How to solve algebraic equations?

• How to find the square root of a number?

What tool is used to generate a number sequence with two rules?

• A ruler

• A protractor

• A calculator

• A T-chart

What is a common mistake when generating number patterns?

• Applying all rules

• Using a T-chart

• Doubling the numbers

• Stopping after the first rule

In the example of doubling and rotating, what is the first step?

• Add one to the number

• Subtract one from the number

• Double the step number

• Rotate the shape clockwise

What is the purpose of using a Double T-chart?

• To draw shapes

• To track the time

• To calculate areas

• To track steps, results, and directions

What is the core pattern of arrow directions in the example of doubling and rotating?

• Left, down, right, up

• Down, left, up, right

• 7

• 6

• 5

• 8

What is the direction of the arrow after step 4 in the example of doubling and rotating?

• Up

• Right
