Hundreds chart
Here is a 100s chart. Answer the following questions to code the chart.
Complete the Hundreds Chart in your notebook or use the following fillable and printable document.

- Underline, draw a symbol (!,@) on, or highlight on the hundred chart every number that ends in zero.
What do you notice? What is the same about all the numbers you marked? What is different about those numbers?
Press ‘Answer’ to find the answer to the problem.
10, 20, 30, 40, 50, 60, 70, 80, 90, 100 - all numbers have zeroes at the end and the first number changes. It goes up by 1.
- Circle, highlight or draw a square around 5. Now skip count by 5 and circle all the numbers you land on. (5, 10, 15, 20...)
What do you notice? What is the same about all the numbers you landed on? What is different about those numbers? Did you land on any of the numbers that end in zero?
Press ‘Answer’ to find the answer to the problem.
5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100 I notice that all the numbers I marked are in two straight lines. I notice that all the numbers have a 5 or a zero at the end. I notice that there are always 2 numbers that have the same number first (10, 15- both have a 1; 40, 45- both have a 4.)
- Draw a cloud on, or a different symbol than one you used before, or highlight 2. Skip count by 2 and make a mark on all the numbers you land on. (2, 4, 6, 8...) What do you notice? What is the same about all the numbers you landed on? What is different? Did you land on any of the numbers that you had already marked? Why do you think this might be?
Take a moment to review the numbers you have highlighted. What patterns do you notice?
Press ‘Answer’ to find the answer to the problem.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 100
All the numbers I landed on are even. They can all be split in half or in two equal groups.
I notice that 2, 4, 6, 8, 0 repeat but the number in front changes.
I only land on some of the squares that I marked when I skip counted by 5s- the ones with the zeroes- the tens. I never land on any of the numbers that end in 5. I think that is because I can split those numbers into two equal groups.
I landed on all the ones that end in zero. Those groups can all be split in half or in two.
Action
Skip counting
We can use skip counting in lots of things.
When we skip count, we are counting by something other than 1.
We are skipping the numbers in between.
We use skip counting when we have money. We count by 5s when we count nickels. We count by 10 when we count dimes.
Let's count!
Follow the directions and identify the pattern for the following questions.

- Start at 2 and count forward 10 squares. Draw an x. Repeat. Continue until there are no more squares. What pattern do you notice with the x’s?
Can you see a pattern? You started at 2. How are the numbers like the number you started with?
Press ‘Answer’ to find the answer to the problem.

62 |
All the numbers end in 2. and all the numbers are even.
- Start at 48. Now skip count by 10s by counting back 10 squares and mark the result with an equal sign. Continue until you run out of squares.
Can you see a pattern? You started at 48. How are the numbers like the number you started at?
Why do you think you have to stop at 8?

38 |
28 |
18 |
8 |
All the numbers end in 8. The first number gets smaller every time (we subtract 1). I think I have to stop at 8 because there aren’t enough spaces to go back 10. 8 is smaller than 10.
- Start at 51 and count forward 5 squares. Draw a smiley face. Continue until you run out of squares. What pattern do you notice? Can you see a pattern? You started at 51. How are the numbers like the number you started at?
When did you run out of squares?

96 |
All the numbers end in a 1 or a 6. I ran out of squares at 96.
I notice that 1 and 6 are repeating and all the numbers are in the same column, above and below each other.

Consolidation
Growing and shrinking patterns
A pattern is a group of numbers, letters or symbols that follow a rule.
Patterns can be growing (getting bigger) or shrinking (getting smaller).
Complete the Hundreds Chart in your notebook or use the following fillable and printable document to create your own growing and shrinking patterns.
Press the ‘Activity’ button to access the Hundreds Chart.
Will you go up or down by numbers other than 2, 5, and 10?
Create a pattern.
Did you create a growing or shrinking pattern? How do you know?
How are the numbers changing in your pattern? How are they staying the same?
Record your ideas orally, using a digital 100s chart, or another tool of your choice.
Think about your learning
How did using a hundreds chart help you to see patterns?
What happens when you skip count by 2? 5? 10? How do the numbers change? How do they stay the same?
How do you know if a pattern is a growing pattern?
How do you know if a pattern is a shrinking pattern?
