Question I. 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. H: 3, Th: 7, O: 5, T: 4  →  Th H T O: _______________
2. Th: 8, H: 0, T: 2, O: 6  →  Th H T O: _______________
3. O: 4, Th: 7, T: 3, H: 7  →  Th H T O: _______________
4. H: 6, O: 6, T: 6, Th: 6  →  Th H T O: _______________

a. ASCENDING ORDER: __________________________________
b. DESCENDING ORDER: __________________________________
c. NUMBER NAME :
1. ___________________________________________
2. ___________________________________________
3. ___________________________________________
4. ___________________________________________
Answer:
First, we arrange each set of dice into Thousands (Th), Hundreds (H), Tens (T), and Ones (O) place value order:
1. Th H T O = 7345
2. Th H T O = 8026
3. Th H T O = 7734
4. Th H T O = 6666

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

c. NUMBER NAME:
1. Seven thousand three hundred forty-five
2. Eight thousand twenty-six
3. Seven thousand seven hundred thirty-four
4. Six thousand six hundred sixty-six
In simple words: Find the number by putting the digits in thousands, hundreds, tens, and ones places first. Ascending order means organizing numbers from smallest to largest, while descending order means from largest to smallest.

Exam Tip: Be careful with the spelling of number names. For example, make sure to write "forty" instead of "fourty".

Question II. FIND THE PRODUCT:
1. 198 x 8
2. 64 X 32
Answer:
1. 198 x 8 = 1584
Working:
\( \begin{array}{r@{\quad}l} & \phantom{0} \text{7} \ \text{6} \\ & \phantom{0} 1 \ 9 \ 8 \\ \times & \phantom{0 0 0} 8 \\ \hline & 1 \ 5 \ 8 \ 4 \end{array} \)

2. 64 x 32 = 2048
Working:
\( \begin{array}{r@{\quad}l} & \phantom{0} 6 \ 4 \\ \times & \phantom{0} 3 \ 2 \\ \hline & 1 \ 2 \ 8 \quad \text{(64 } \times \text{ 2)} \\ + & 1 \ 9 \ 2 \ 0 \quad \text{(64 } \times \text{ 30)} \\ \hline & 2 \ 0 \ 4 \ 8 \end{array} \)
In simple words: Multiply the numbers to find their product. 198 times 8 is 1584, and 64 times 32 is 2048.

Exam Tip: Show all carry-over digits and step-by-step additions clearly so your teacher can easily check your working.

Question III. Find the multiplication fact and division fact using the groups shown

1.
[4 groups of 3 stars]
2.
[3 groups of 5 faces]
Answer:
1. For the stars (4 groups of 3):
- Multiplication Fact 1: 4 x 3 = 12
- Multiplication Fact 2: 3 x 4 = 12
- Division Fact 1: 12 ÷ 4 = 3
- Division Fact 2: 12 ÷ 3 = 4

2. For the faces (3 groups of 5):
- Multiplication Fact 1: 3 x 5 = 15
- Multiplication Fact 2: 5 x 3 = 15
- Division Fact 1: 15 ÷ 3 = 5
- Division Fact 2: 15 ÷ 5 = 3
In simple words: Multiplication counts how many things we have in equal groups. Division splits the total number of things back into equal groups.

Exam Tip: Remember that division is the exact opposite of multiplication. You can use the same three numbers to write both facts.

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

a) Rectangle
- Vertices (Corners): 4
- Sides: 4

b) Triangle
- Vertices (Corners): 3
- Sides: 3

2. Two Solid Shapes (3D Shapes):

a) Cube
- Vertices (Corners): 8
- Edges (Sides): 12

b) Cone
- Vertices (Corners): 1 (the top point/apex)
- Edges (Sides): 1 (the round circular base)

In simple words: Plane shapes are flat drawings on paper. Solid shapes are 3D objects you can hold in your hand. Vertices are the pointy corners of these shapes.

Exam Tip: Remember that flat shapes have "sides" but solid shapes have "edges" and "faces".
