CBSE Class 3 Mathematics Revision Worksheet Set 13

Question 1. Four dices are thrown at the same time , each die show a number with place value. Arrange these numbers according to the place value, ascending and descending order, and also write the number name.
1. Dice: H = 3, Th = 7, O = 5, T = 4
2. Dice: Th = 8, H = 0, T = 2, O = 6
3. Dice: O = 4, Th = 7, T = 3, H = 7
4. Dice: H = 6, O = 6, T = 6, Th = 6
Answer:
Place Value Arrangement (Th H T O):
1. 7345
2. 8026
3. 7734
4. 6666

a. ASCENDING ORDER:
6666, 7345, 7734, 8026

b. DESCENDING ORDER:
8026, 7734, 7345, 6666

c. NUMBER NAME :
1. 7345 - Seven thousand three hundred forty-five
2. 8026 - Eight thousand twenty-six
3. 7734 - Seven thousand seven hundred thirty-four
4. 6666 - Six thousand six hundred sixty-six
In simple words: First, place each digit under its correct column (Thousands, Hundreds, Tens, and Ones) to form the numbers. Then, arrange those numbers from smallest to largest for ascending order, and from largest to smallest for descending order. Finally, write each number using words.

Exam Tip: Be careful with the order of the dice shown in the diagrams! Look closely at the place value letter (Th, H, T, O) above each die before writing down the number.

Question 2. FIND THE PRODUCT:
1. 198 x 8
2. 64 X 32
Answer:
1. 198 x 8 = 1584
2. 64 x 32 = 2048
In simple words: Multiply the numbers step-by-step to find the total product.

Exam Tip: When multiplying by a two-digit number (like 32), always remember to put a placeholder zero in the ones column before you start multiplying by the tens digit (3).

Question 3. Find the multiplication fact and division fact using the groups shown
1. 4 groups of 3 stars each
2. 3 groups of 5 smiley faces each
Answer:
1. Stars (4 groups of 3):
Multiplication Fact: 4 x 3 = 12 (or 3 x 4 = 12)
Division Fact: 12 / 3 = 4 (or 12 / 4 = 3)

2. Smiley Faces (3 groups of 5):
Multiplication Fact: 3 x 5 = 15 (or 5 x 3 = 15)
Division Fact: 15 / 5 = 3 (or 15 / 3 = 5)
In simple words: Multiplication tells us the total amount when we put equal groups together. Division tells us how to split that total back into equal groups.

Exam Tip: A group of objects can represent a family of related facts. Practice writing both the multiplication and division forms to verify your calculation.

Question 4. Draw any two plane shapes and 2 solid shapes and write the number of vertices and sides for each.
Answer:
1. Plane Shapes (2D flat shapes):

Triangle:
- Vertices (corners): 3
- Sides: 3

Rectangle:
- Vertices (corners): 4
- Sides: 4

2. Solid Shapes (3D shapes):

Cube:
- Vertices (corners): 8
- Faces (flat surfaces): 6
- Edges: 12

Cone:
- Vertices (apex corner): 1
- Faces (surfaces): 2 (1 flat face and 1 curved face)
- Edges (borders): 1 curved edge
In simple words: Plane shapes are completely flat, having only corners and edges. Solid shapes are 3D shapes that also have depth, having flat surfaces called faces.

Exam Tip: For 3D solid shapes, be sure to count all the hidden corners and lines. Using a real object (like a box for a cube) can help you count correctly.
