Skip-Counting by 10s and 100s with Base-10 Blocks

This video tutorial introduces skip-counting, a method to count more efficiently by using increments larger than one. It explains how to skip-count by 10s and 100s using base-10 blocks, demonstrating the patterns that emerge in the tens and hundreds places. The tutorial also covers decreasing patterns by subtracting the same amount each time, emphasizing that skip-counting can start from any number and can be done both forward and backward.

What is skip-counting?

• Counting by an amount larger than 1

• Counting by 1s

• Counting by 2s

• Counting backward

When skip-counting by 10s, what happens to the tens place?

• It decreases by 1

• It stays the same

• It increases by 1

• It doubles

What occurs when you reach 10 tens while skip-counting by 10s?

• The tens place resets to 0

• The hundreds place increases by 1

• The number becomes negative

• The tens place decreases by 1

How does the hundreds place change when skip-counting by 100s?

• It doubles

• It decreases by 1

• It stays the same

• It increases by 1

What is a key characteristic of decreasing patterns in skip-counting?

• Subtracting different amounts each time

• Subtracting the same amount each time

• Adding the same amount each time

• Starting from zero
