Fraction Estimation 6 1 3 5 Estimate solutions

Fraction Estimation 6. 1. 3. 5 Estimate solutions to problems with whole numbers, fractions, and decimals and use the estimates to assess the reasonableness of results in the context of the problem.

I can… Estimate fractions and mixed numbers using benchmark fractions Self Assessment 5 - I can do it without help & teach others. 4 - I can do this with no help, but I don’t know if I can explain it. 3 - I can do this with a little help. 2 - I can do this with a lot of help! 1 - I don’t have a clue.

Rules… �To round a fraction to the nearest benchmark, use the following rules: ◦ If the numerator is much less than the denominator, we round the fraction to 0. ◦ If the numerator is about ½ of the denominator we round the fraction to ½. ◦ If the numerator is much more than the denominator, we round the fraction to 1.

Examples �Round 0 �Since ¾ 1 4 2 4 3 4 1 ¾ is greater than ½, we round up to 1 �Therefore, ¾ rounded to the nearest whole number is 1

Examples �Round 0 �Since ¼ to the nearest whole number 1 4 2 4 3 4 1 ¼ is less than ½, we round down to 0 �Therefore, ¼ rounded to the nearest whole number is 0

Examples 2 �Round 4 to the nearest whole number 0 1 4 �Since 2 4 3 4 1 is equal to ½, we round up to 1 2 �Therefore, 4 rounded to the nearest whole number is 1
