There is one type of problem in this exercise:
- Select the answers: This problem has two number with an identical digit in different place values. The user is supposed to answer three questions by selecting the correct option from a drop-down menu.
This exercise is easy to get accuracy badges once the user understands what they are asking for. The speed badges are medium-hard to get because the learner has to select options on different questions so the learner has to be fast with the mouse or tabbing.
- Find the number that is common and of interest, and count how many spots, this will help the learner get the first two answers.
- If the answer was that it was to the "left", then it is larger.
- If the answer was that it was to the "right", then it is as large.
- In other words, left larger, right smaller (fraction).
- Decimals appear in every-day media to display information to consumers.
- Decimals are very common in shopping. Price tags, food labels, and receipts all contain decimals.
- At gas pumps, decimals are used to show how much gas is pumped and much it costs per gallon.
