Video Transcript

Count on to add. Find the total, 12 plus six.

Number 12 has already been highlighted. That’s where we need to begin counting. And we need to add six. That means we should start at 12 and count on six more.

One, two, three, four, five, six, we landed on number 18. So we can say that 12 add six equals 18. We found our answer by counting forward six more places on the number line.
