Hundreds Chart and Skip Counting Studio

Skip counting means jumping forward by the same number each time instead of counting one by one.

• Count by 2s: 2, 4, 6, 8, 10...
• Count by 5s: 5, 10, 15, 20, 25...
• Count by 10s: 10, 20, 30, 40, 50...

Skip counting is a fast way to count large groups and builds the foundation for multiplication.

Every skip count makes a visual shape on the chart.

• Counting by 2s highlights every other column in a checkerboard stripe.
• Counting by 5s highlights two columns: 5 and 10 in each row.
• Counting by 10s fills the entire last column (10, 20, 30...).

Look for diagonal, vertical, or zigzag patterns as you change the interval.

Fives and tens are the easiest skip counts to learn because they match our fingers.

• Every multiple of 5 ends in 0 or 5.
• Every multiple of 10 ends in 0.
• Two groups of 5 always equal one group of 10.

These patterns appear on clocks, rulers, and money. Knowing them by heart makes everyday math faster.

A hundreds chart is a 10-by-10 grid with numbers 1 to 100. Each row holds 10 numbers, and each column holds numbers that share the same ones digit.

• Moving right adds 1.
• Moving down adds 10.
• Moving diagonally down-right adds 11.

Use the chart to add, subtract, and spot number relationships at a glance.
