Lesson 3: Equivalent Fractions 12-01-2016 L.O. To understand equivalent fractions: 1/2s, 1/3s, 1/4s, 1/5s, 1/6s 1/8s, 1/10s I can identify equivalent fractions including 2/3, 3/4 . I can identify equivalent fractions for ½, ¼ and 1/3.   I can begin to compare fractions with different denominators.

Lesson 3 12-01-2016 L.O. To understand equivalent fractions: 1/2s, 1/3s, 1/4s, 1/5s, 1/6s 1/8s, 1/10s Working in pairs, count each fraction carefully and write in the fractions for each of the discs on your sheet. Colour each one a different colour and cut them all out.

Lesson 3 12-01-2016 L.O. To understand equivalent fractions: 1/2s, 1/3s, 1/4s, 1/5s, 1/6s 1/8s, 1/10s Use your fraction discs to find an equivalent fraction for ½ Are there any other fractions that make up a half? Which fractions are the equivalent of: 1 / 3 1 / 4 1/5 These equivalent fractions make up FRACTION FAMILIES.

Lesson 4 13-01-2016 L.O. To find fractions of amounts. Fractions in a Box We have a game which has a number of discs in seven different colours. These are kept in a flat square box with a square hole for each disc. There are 10 holes in each row and  10 in each column. So, there would be 100 discs altogether, except that there is a square booklet which is kept in a corner of the box in place of some of the holes.

Lesson 4 13-01-2016 L.O. To find fractions of amounts. Fractions in a Box There is a different number of discs of each of the seven colours. Half (1/2 ) of the discs are red, 1/4 are black and 1/12 are blue. One complete row (of 10 holes) of the box is filled with all the blue and green discs. One of the shortened rows (that is where the booklet is) is exactly filled with all the orange discs. Two of the shortened rows are filled with some of the red discs and the rest of the red discs exactly fill a number of complete rows (of 10) in the box. There is just one white disc and all the rest are yellow. How many discs are there altogether? What fraction of them are orange? What fraction are green? Yellow? White?

Lesson 4: Equivalent Fractions 13-01-2016 L.O. To use equivalence to reduce fractions to their simplest form. I know the simplest form of a fraction . I can list fraction families   I can identify equivalent fractions

Lesson 4 – Fraction Families 13-01-2016 L.O. To use equivalence to reduce fractions to their simplest form. Each equivalent fraction is part of a fraction family. Can you see a fraction which is equivalent to ½? List as many fractions as you can that are equivalent to 1/2 , ¼ and 1/3.

Lesson 4 – Fraction Families 13-01-2016 L.O. To use equivalence to reduce fractions to their simplest form. Each equivalent fraction is part of a fraction family. When we write fractions we try to write them in their simplest form (the smallest numerator and denominator possible). Therefore, when we simplify fractions we look for the first fraction in the family. Use your fraction discs that are equivalent to ½. Put them in order from first to last.

Lesson 4 – Fraction Families 13-01-2016 L.O. To use equivalence to reduce fractions to their simplest form. Each equivalent fraction is part of a fraction family. Which fractions are equivalent to: Which fraction is the first in this fraction family?

The principal wants there to be the same number of children in every class. How will we find out how many children will be in each class? How can we write the fraction for two classes? What fraction will six classes be?

Lesson 5: Investigation 14-01-2016 L.O. To find fractions of amounts and relate division and multiplication Complete the table to find out how many children in two classes, three, four and so on. Yellow to copy the table, Red and Green to complete handout and glue in their investigation books.

Lesson 5: Investigation 14-01-2016 L.O. To find fractions of amounts and relate division and multiplication 1. 5/10 of 400 = 200 What fraction of the school is this? Can we simplify this fraction?
