Halloween Math & Reading — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. 7 + 8 = 15
The prefix 'tri' means three, so a triangle is any closed shape with exactly three straight sides and three angles.
2. A witch rides a broomstick.
Perimeter measures the total distance around a shape. Add up all the side lengths to find how far it is to walk around the outside.
3. 14 - 6 = 8
Area tells you how much surface a flat shape covers. It is measured in square units, like counting how many tiles fit inside.
4. You say trick or treat at each door.
Volume measures how much space a 3D object holds inside, like how many small cubes can fit inside a box.
5. 6 + 9 = 15
One meter equals 100 centimeters. The prefix 'centi' means one hundredth, so a centimeter is one hundredth of a meter.
6. A skeleton is made of bones.
'Kilo' means one thousand, so one kilogram is made up of exactly 1,000 grams.
7. 17 - 8 = 9
Volume of a box uses three measurements: length, width, and height. Multiply all three together to find how much space the box holds.
8. Owls come out at night.
A line of symmetry splits a shape so that one half mirrors the other perfectly, like folding a paper heart exactly in half.
9. 12 + 5 = 17
A right angle is exactly 90 degrees, forming a perfect square corner. Look at the corner of a book or a window to see one.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
pumpkin
→ orange fruit
wrapped in cloth
mummy
→ wrapped in cloth
hoots at night
owl
→ hoots at night
sweet treat
candy
→ sweet treat
orange fruit
Correct matches: A pumpkin box is 2 ft × 3 ft × 4 ft → 24 cubic feet; A square graveyard fence is 10 m on each side → 40 meters; A spider web covers a 6 in × 6 in area → 36 square inches; A cauldron holds 3,000 mL of potion → 3 liters.
