Daniel recorded the number of glasses of juice he sells in his neighborhood each day in this tally chart. How many more glasses were sold on Thursday than Friday and Monday combined?

We know the tally chart tells us the number of glasses of juice Daniel sells in his neighborhood each day. How many glasses of juice did he sell on Monday? We know that this is how we show five using tally marks. We know that five plus two gives us a total of seven. How many did he sell on Tuesday? We’ve got two fives plus four more, which makes 14. On Wednesday, there are three fives plus one more: five, 10, 15, 16. He sold a lot of juice on Thursday: five, 10, 15, 20, and one more makes 21. On Friday, he sold five, 10 glasses of juice.

The question asks us how many more glasses of juice were sold on Thursday than on Friday and Monday combined. To combine the number of glasses he sold on Friday and Monday, we need to add these two totals together. On Friday, Daniel sold 10 glasses of juice. And on Monday, he sold seven. We know that 10 plus seven is 17. We know that 21 glasses of juice were sold on Thursday.

Now, we need to find the difference between 21 and 17. To find the difference, we could count forward starting at 17 until we reach 21. One, two, three, four. The difference between 17 and 21 is four. Four more glasses of juice were sold on Thursday than Friday and Monday combined. We read the information in the tally chart and used it to help us solve the problem.
