   • 10:30-11:30 is one hour. (That’s 3 hours.)
   • 11:30-12:30 is one hour. (That’s 4 hours.)
   • 12:30-1:00 is half an hour. (That’s 4 and a half hours.)
2. Make the correct amount of time pass, or elapse.
   • Try “to the hour” and “to the half-hour“.

1. Try to find the equivalent fractions. Drag the picture from the top onto the match on the bottom. They are just being introduced to equivalent fractions. They aren’t supposed to be figuring them out. They are to use the images to image how much of the whole the fraction represents.
   • First, count the pieces in an image in the top. That’s the denominator. Then, count the pieces that are colored in. That’s the numerator. Find that fraction in the bottom.
   • Do that for all the images on top. Then work on the fractions as described below.
   • I held up fingers for the number in the denominator. Then I bent down fingers leaving the number in the numerator. Is it most of them? Not very many of them? If it is most of them, then most of the picture would be colored in.

   • You don’t need to know the names of all of those properties, but it’s good to know these things. Read below.
   • Multiplication is adding over and over again. 5 times 2 is 5 + 5, 5 times 3 is 5 + 5 + 5, 5 times 4 is 5 + 5 + 5 + 5. That’s like counting by fives 4 times.
   • If I put five books on each shelf and there were four shelves, I would have 5 + 5 + 5 + 5 books. 5 x 4 = 20
   • Anything zero times is zero. A million times zero is zero. If I gave you a million dollars zero times, you would have zero dollars.
   • Anything one time is itself. 8 times 1 is 8. If I give you eight pieces of candy one time, you would have eight pieces of candy.
   • 3 times 2 is the same as 2 times 3 (just like addition). If I gave you 3 M&Ms two times, you would have 6. If I gave you 2 M&Ms three times, you would have 6. If you don’t believe me, go ask for some chocolate chips to practice with. Give 3 two times and 2 three times and see if it’s the same amount. 2 x 3 = 3 x 2 = 6
2. Learn that any number times zero is zero.
