3. A square is divided into 4 equal parts. Each part is a smaller square. How many smaller squares are there? Answer: 4 Solution: 1. The problem says we have a square. This is one large square.
   Full step-by-step solution

   Let's go step-by-step. 1. The problem says we have a square. This is one large square. 2. It is divided into 4 equal parts. Each part is a smaller square. 3. Since each part is a smaller square, and there are 4 equal parts, the number of smaller squares is simply 4. 4. We can visualize: If you draw a large square and divide it with one vertical line and one horizontal line through the center, you get 4 smaller squares of equal size. 5. Therefore, the total number of smaller squares is 4. ANSWER: 4

4. Mati drew a large square on paper. He wants to cut it into 4 equal parts. What is each equal part called? Answer: a fourth (or one quarter) Solution: Mati starts with one whole square. Step 2: He cuts it into 4 equal parts. Step 3: When a shape is divided into 4 equal parts, each part is called a fourth (or one quarter).
   Full step-by-step solution

   Step 1: Mati starts with one whole square. Step 2: He cuts it into 4 equal parts. Step 3: When a shape is divided into 4 equal parts, each part is called a fourth (or one quarter). The answer is a fourth (or one quarter).

5. Emma has a rectangular sheet of paper. She folds it into 8 equal parts. If she colors 3 parts blue, how many parts are not colored? Answer: 5 Solution: Emma folds the paper into 8 equal parts. She colors 3 parts blue. To find how many parts are not colored, subtract the colored parts from the total parts: 8 - 3 8 - 3 = 5 The answer is 5.

   Step 1: Emma folds the paper into 8 equal parts. Step 2: She colors 3 parts blue. Step 3: To find how many parts are not colored, subtract the colored parts from the total parts: 8 - 3 Step 4: 8 - 3 = 5 The answer is 5.

6. A rectangle has 2 rows of circles. Each row has 6 circles. How many circles are there in total? Answer: 12 Solution: There are 2 rows of circles. Each row has 6 circles. To find the total, add the number of circles in each row: 6 + 6 6 + 6 = 12 The answer is 12.
   Full step-by-step solution

   Step 1: There are 2 rows of circles. Step 2: Each row has 6 circles. Step 3: To find the total, add the number of circles in each row: 6 + 6 Step 4: 6 + 6 = 12 The answer is 12.

7. Liam has a rectangular sheet of stickers with 4 rows. Each row has 3 stickers. How many stickers does Liam have in total? Answer: 12 Solution: Liam has a rectangular sheet of stickers with 4 rows. Each row has 3 stickers. To find the total number of stickers, we multiply the number of rows by the number of stickers in each row.
   Full step-by-step solution

   Liam has a rectangular sheet of stickers with 4 rows. Each row has 3 stickers. To find the total number of stickers, we multiply the number of rows by the number of stickers in each row. Step 1: Identify the number of rows = 4 Step 2: Identify the number of stickers in each row = 3 Step 3: Multiply: 4 × 3 = 12 So, Liam has 12 stickers in total.
