Yesterday we got back into the classroom after being out 2 days for ClassScapes testing. Students were given another outline as we practiced multiplying mixed numbers with fractions, whole numbers, and another mixed number. This was mostly review as this did not require learning any new skills, but instead putting some of the previous skills together. Below are the steps we used when multiplying mixed numbers
1.) Convert any mixed numbers into improper fractions
2.) Convert any whole numbers into fractions (put the # over 1)
3.) Simplify if possible
4.) Multiply numerators / multiply denominators
5.) Convert answer to a mixed number (if possible) and simplify
The homework assignment from last night was workbook page 40
Today we will have our lesson on dividing fractions. Dividing fractions is nothing more than multiplying by the reciprocal.
For example
10 ÷ 2 is the same as 10 x ½
15 ÷ 3 is the same as 15 x 1/3
¼ ÷ ½ is the same as ¼ x 2/1
Our steps for dividing fractions are simply "switch and flip"
This means switch the division sign to a multiplication sign, then flip the fraction we are dividing by (the divisor)
Homework tonight is workbook page 41
Tomorrow we will be doing a team activity to practice all of the fraction operations we have learned so far.
Next week we will begin by adding and subtracting like fractions, then move to adding and subtracting unlike fractions
