Placing rational numbers (fractions and decimals) on a number line builds on locating whole numbers and simple fractions and knowing which way is bigger. Warm up reading a number line and the fraction spots fall into place.
Answer these 3, then press Show my path. No grade — this just points you to the right level.
1. On a number line, where does 1/2 sit?
2. Which number is bigger: 1/2 or 1?
3. What whole number is just to the right of 3 on a number line?
A number line has whole numbers marked: 0, 1, 2, 3… Fractions sit in the spaces between them. For example, 1/2 is halfway between 0 and 1. The farther right, the bigger the number.
Your quick check picks one for you, but you can switch any time:
Level 0 Locate whole numbers first.
A. What whole number is 1 step right of 0?
Right after 0 comes 1.
B. What whole number comes right after 4?
4, then 5.
C. 1/2 is between 0 and which whole number?
1/2 is halfway from 0 to 1.
Level 1 Place simple fractions.
A. Where does 1/2 sit?
Split the 0-to-1 gap in half.
B. Which is greater: 1/2 or 2?
2 is farther right than 1/2.
Level 2 Stretch into mixed numbers.
A. The number 2 1/2 sits between 2 and which whole number?
2 1/2 is halfway from 2 to 3.
B. Which is bigger: 1 1/2 or 1?
1 1/2 is past 1, so it is bigger.
1. Where does 1/2 sit on the number line?
1/2 is the middle of the 0-to-1 gap.
2. 3 1/2 sits between 3 and which whole number?
3 1/2 is halfway from 3 to 4.
