Counting On and Basic Addition

The video tutorial introduces the counting on strategy for addition, demonstrating how to add numbers more efficiently by starting from the larger number and counting up. Examples using marbles, jellyfish, and apple trees illustrate the concept. The tutorial also explains using a number line for counting on and provides advanced examples to reinforce the strategy.

What is the main advantage of the counting on strategy over traditional counting methods?

• It allows you to start from any number.

• It is slower but more accurate.

• It is faster and more efficient.

• It requires no prior knowledge of numbers.

In the marbles example, how many marbles are in the first jar?

• Five

• Three

• Two

• Four

When counting on with marbles, what number do you start counting from?

• Four

• One

• Two

• Three

How many jellyfish are there in total when you have four purple and three green jellyfish?

• Five

• Six

• Eight

• Seven

In the jellyfish example, what is the first number you start counting from?

• Six

• Five

• Four

• Three

What is the total number of apples when one tree has eight and the other has seven?

• Fifteen

• Seventeen

• Sixteen

• Fourteen

When using a number line, what is the first step in counting on?

• Jump to the end of the line.

• Start from the first number.

• Start from zero.

• Count backwards.

On a number line, if you start at six and jump three spaces, where do you land?

• Eight

• Eleven

• Nine

• Ten

What is the mental process involved in counting on?

• Counting backwards.

• Starting from zero each time.

• Locking the smallest number in mind.

• Locking the biggest number in mind.

In the mental process of counting on, what do you do after locking the biggest number in your mind?

• Count on from the locked number.

• Start over.

• Count forwards from zero.

• Count backwards.
