1.Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.

2.Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape

~I am a rectangle made up of 28 same size squares. I have 4 columns. How many rows must I have? Prove your answer with a drawing. How many squares do I have?
~I am a rectangle made up of 24 same size squares. I have 6 rows. How many columns must I have? Prove your answer with a drawing. How many squares do I have?
~I am a rectangle made up of 30 same size squares. How many rows and columns might I have? Show all possible answers through proof drawings.
~Partition a rectangle into 4 rows, 5 columns (Draw what those rows and columns would look like in a given rectangle.)
~Can you partition a rectangle so that you have 7 squares? If so draw the rectangle and tell how many rows and columns you partitioned the rectangle into. If not why do you think you couldn’t get 7 squares?

~They need to know that they can divide shapes into equal pieces and use special words like halves, thirds, etc. to name those shapes. They need to know how to draw lines on a shape to show how to divide into these pieces. They also need to know that the pieces need to be equal.
~Use their knowledge of fractions to solve word problems: Mr. Olbertz is planting 14 roses in his garden. He wants half of them to be yellow and half of them to be red. How many roses will be yellow? How many roses will be red? OR Melissa plans to share an extra large pizza with her 3 friends – Angela, Darlene, and Beatrice. The pizza has 12 slices. Melissa said each person should get one-fourth of the pizza. Angela said each girl should get one-third of the pizza. Who is correct? How do you know? How many slices of pizza will each girl get? Use pictures, words, and fractions to show your work and solve.

and also where can i get these type of questions
