StandardUnderstand a fraction is part of a whole when divided into equal parts
|
Core Standard3.NF.1 Understand a fraction 1/b as the quantity formed by 1 part when a whole is partioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b
|
In Other Words...For a number to be a fraction, the parts must all be equal. If I see 1/3 then I know the whole was divided into 3 equal parts and I am seeing one of them. It is understanding what the numerator and denominator represent in the fraction. So, 3/5 shows that 3 of the 5 equal parts are being shown.

If MasteredOn level 3 and 4 of this website, you match mixed numbers and their pictures. Click Here
This website has estimating the distance in fractional amounts. Click Here |
If Not Yet MasteredGive your child as much exposure to fractions as you can. When you're cooking allow them to do it with you and experience how a half is bigger than a third. When cutting something into fourths to share with everyone, talk to your child about what you're doing and how many pieces you should cut it into. If you're ordering pizza with half and half of toppings show them how the sections are halves when the pizza comes. Take any opportunity to encounter fractions in real life to expose your child to the fraction and what makes it a fraction. Here is a great website. It has a great fraction tutorial in the beginning and then goes on to a matching game where they match the fraction to the shape. Click Here This website has great tutorials and some practice. Your child should do number 1 and number 3. Click Here Here is a great matching fractions with their picture game. Click Here Here is a matching game of the fraction and a picture that represents that fraction. Click Here

Core Standard3.NF.2 Understand a fraction as a number on the number line diagram. a. Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has the size 1/b ad the endpoint of the part based at 0 locates the number 1/b on the number line. b. Represent a fraction a/b on a number line diagram by marking off a length 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.

This website has an activity similar to Pacman that has students identify numbers on a number line. Click Here. |
If Not Yet MasteredThis website shows the fractions on the number line and has some equivalent fractions. It has a great reteaching tool if they get it wrong. Click Here This website has you place fractions on a number line. Click Here This website has you identify fractions on a number line, but also shows the fraction squares which may help see where it is on the number line.

StandardUnderstand equivalent fractions.

Core Standard3.NF. 3 Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size. a. Understand two fractions as equivalent (equal) if they are the same size, or the same point on the number line. b. Recognize and generate simple equivalent fractions, e.g. 1/2 = 2/4, 4/6 = 2/3. Explain why the fractions are equivalent, e.g., by using a visual fraction model. c. Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers. Examples: Express 3 in the form of 3 = 3/1; recognize that 6/1 = 6; locate 4/4 and 1 at the same point of a number line diagram. d. Compare two fractions with the same numerator or the same denominator by reasoning about their size. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparison with the symbols >, + , or <, and justify the conclusion, e.g., by using a visual fraction model.
|
In Other Words...When the whole starts the same and then fractions are divided from that whole, some of them will be equal to each other. For example, 1/3 will be the same size as 2/6. This will also be the same on a number line. Every number can be represented as a fraction. 3 is 3/1 and 1 is the same as 6/6 or any other number that has the same numerator and denominator (10/10, 2/2, etc.)

If MasteredThis activity that allows students to match equivalent fractions. Click Here.
The website has students compare fractions. Have your child see if they can decide which will be bigger before they show it on the screen. Click Here |
If Not Yet MasteredThis website let's you pick the fractions to compare and they visually show the pieces to you. Click Here Students could work with games that go to harder equivalent fractions like Click Here. This one has some harder fractions, but this should help with their multiplying and dividing skills as well, or they will be exposed to which fractions are equivalent as they correctly match them. This activity has 5 levels. The first few should be fairly easy for them, but it gives a variety of activities like telling the fraction of the shaded part, putting things on a number line, etc. Click Here Here is a sight that allows you to compare fractions.

In Other Words...When the whole starts the same we can compare fractions that either have
the same numerator or denominator. If the numerator is the same, the smaller the denominator the bigger the fraction. 1/2 is bigger than 1/3, so 2/7 is bigger than 2/9. When looking at the same denominator, the bigger numerator shows the bigger fraction. So, 3/4 is bigger than 1/4. |
