3.OA.3 MULTIPLICATION AND DIVISION STRATEGIES ARRAYS AND DRAWINGS

GROUP SIZE UNKNOWN - ARRAY If 18 apples are arranged into 3 equal groups. How many apples will be in each group?

NUMBER OF GROUPS UNKNOWN - ARRAY I have 28 pieces of gum for my friends. Each friend gets 4 pieces. How many friends do I have?

UNKNOWN PRODUCT - ARRAY What multiplication problem is represented by the drawing below?

PRODUCT UNKNOWN– AREA MODEL ARRAY I have 18 packs of markers. Each pack has 4 markers in it. How many markers do I have in total? total markers 4032

TRUE OR FALSE My friend multiplied these two numbers. Below is their reasoning. Are they correct? If not, what advice do you have for this student? 18 x 6 =

WRITE A WORD PROBLEM REPRESENTED BY THE DRAWING

DIVISION - AREA MODEL ARRAY GROUP SIZE UNKNOWN If you have 48 inches of ribbon cut into 6 pieces, how long will each piece measure? 48 inches of Ribbon 6 pieces 3 X 6 = 18 5 X 6 = 30

DIVISION – ARRAY NUMBER OF GROUPS UNKNOWN If 56 pieces of fruit are to be packed 4 to a bag. How many bags will be needed? Use a drawing or array to solve. Be prepared to share your answer and explain.

DIVISION – ARRAY NUMBER OF GROUPS UNKNOWN Same Problem - If 56 pieces of fruit are to be packed 4 to a bag. How many bags will be needed? Can you explain this drawing? Is it correct? Is there anything missing?

DIVISION – ARRAY NUMBER OF GROUPS UNKNOWN Same Problem - If 56 pieces of fruit are to be packed 4 to a bag. How many bags will be needed? Can you explain this array? Is it correct? Is there anything missing?
