### Extra Help Problems

 (1) A worksheet focusing on length. Have compare small objects to one another. Use a penny as a reference. (2) Ex. Mouse= 6 pennies pencil=14 pennies glasses= 10 pennies Have the student circle the smallest object and underline the longest object. (3) Book=25 pennies shoe= 17 pennies sock=15 pennies (4) Cup= 10 pennies plate= 14 pennies fork= 11 pennies (5) Ball= 13 pennies football= 19 pennies basketball= 18 pennies (6) Glasses= 9 pennies video= 12 pennies CD= 8 pennies (7) The next worksheet can focus on volume. Ex: A small soda bottle= 2 cups a pot= 8 cups a gallon= 16 cups. Ask the student to circle the object that holds the least amount of liquid and to underline the object that holds the most liquid. (8) Tub= 250 cups bowl= 3 cups mug= 2 cups (9) Pan= 8 cups vase= 12 cups saucepan= 6 cups (10) Quart= 4 cups pint= 2 cups gallon= 16 cups (11) Kettle= 8 cups pot= 20 cups sink= 50 cups (12) A worksheet will focus on weight. Compare smaller objects to a pillow. Ex: a cat = 1 pillow a baby= 3 pillows a chair = 12 pillows The student can be asked to circle the lightest object and to underline the heaviest object. (13) Backpack=10 pillows book= 1 pillow shoe= ½ pillow (14) Chair= 20 pillows computer= 30 pillows dog= 10 pillows (15) Mom= 40 pillows Dad= 50 pillows You= 35 pillows (16) Elephant= 500 pillows monkey= 25 pillows horse= 300 pillows
