Day 8
- Draw three columns at the board. At the top of one write "less than 1/2," at the top of the next, write "= 1/2," and at the top of the last column
write "more than 1/2." I'll give you some fractions. You write them in the correct column: 5/8, 1/21, 91/100, 7/13, 6/12, 9/18, 3/3.
- Write five fractions equivalent to 1.
- Write five fractions larger than 1.
- Write five fractions smaller than 1.
- Draw three columns. At the top of one write "less than 1," at the top of the next, write "= 1," and at the top of the last column write "more than 1."
I'll give you some fractions. You write them in the correct column: 5/8, 4/4, 9/10, 3/2, 7/7, 4/1, 6/6.
- I'll give you three fractions, 1/6, 10/10 and 6/4. Write them in order from smallest to largest. Think about whether they are bigger or smaller than 1,
or equivalent to 1.
- I'll give you five fractions, 5/3, 1/3, 2/3, 3/3 and 10/3. Write them in order from smallest to largest.
- Write some equivalent fractions: 1/4 = /16; 2/3 = /21; 3/5 = /40; 3/8 = /32; 5/9 = /45.
- The third quarter of the football game is over. What fraction of the game is left to play?
- Four team mates run a relay race. What fraction of the race does each person run?
- Reduce these fractions to lowest terms: 4/10, 7/21, 8/16, 6/18, 5/25, 7/56.
- Add: 1/2 + 1/2; 1/2 + 1/4; 1/2 + 1/8.
- Subtract: 1/2 - 1/2; 1/2 - 1/4; 1/2 - 1/8.
Following days
Many days of board work follow this pattern-adding and subtracting, multiplying and dividing fractions, continuing to build up a sense in students of the
relative size of fractions and mixed numbers.
