💡 1st Grade Math: Addition and Subtraction Practice Questions

Let's count Mia's apples! 🍎🍏

• Step 1: Identify the numbers. Mia has 3 red apples and 2 green apples.
• Step 2: To find the total, we need to add the numbers together.
• Step 3: Write the addition problem: \( 3 + 2 \)
• Step 4: Count them all: 1, 2, 3 (red apples) and 4, 5 (green apples).
• Step 5: The answer is 5.

So, Mia has \( 3 + 2 = 5 \) apples in total. ✅

Let's find out how many birds stayed! 🐦

• Step 1: Start with the total number of birds: 7.
• Step 2: Identify how many birds left: 3.
• Step 3: When birds fly away, it means we take them away, so we subtract.
• Step 4: Write the subtraction problem: \( 7 - 3 \)
• Step 5: Count back from 7: 6, 5, 4.
• Step 6: The answer is 4.

So, there are \( 7 - 3 = 4 \) birds left on the branch. ✅

Let's add up all of Tom's colorful marbles! 🔵🟢🟡

• Step 1: Identify the number of each color of marble: 5 blue, 4 green, and 1 yellow.
• Step 2: To find the total, we add all the numbers together.
• Step 3: Write the addition problem: \( 5 + 4 + 1 \)
• Step 4: Add the first two numbers: \( 5 + 4 = 9 \).
• Step 5: Now add the last number to that sum: \( 9 + 1 = 10 \).
• Step 6: The answer is 10.

Tom collected \( 5 + 4 + 1 = 10 \) marbles altogether. ✅

Let's see how many stickers Lily has left after sharing! ✨

• Step 1: Lily started with 12 stickers.
• Step 2: She gave away 5 stickers. When you give something away, you subtract.
• Step 3: Write the subtraction problem: \( 12 - 5 \)
• Step 4: You can count back 5 from 12: 11, 10, 9, 8, 7.
• Step 5: The answer is 7.

Lily has \( 12 - 5 = 7 \) stickers now. ✅

This problem has two parts! Let's solve it step-by-step. 🍪

• Step 1: Find out how many cookies Sarah's brother has.
• Sarah has 8 cookies. Her brother has 3 fewer, so we subtract: \( 8 - 3 = 5 \).
• Her brother has 5 cookies.
• Step 2: Find the total number of cookies they have altogether.
• Sarah has 8 cookies and her brother has 5 cookies.
• Add their cookies together: \( 8 + 5 = 13 \).

They have \( 8 + 5 = 13 \) cookies altogether. ✅

Let's count all the kids having fun at the park! 🤸🎢

• Step 1: Identify the number of kids on swings: 6.
• Step 2: Identify the number of kids on the slide: 4.
• Step 3: To find the total number of kids, we need to add.
• Step 4: Write the addition problem: \( 6 + 4 \)
• Step 5: Count them together: \( 6 + 4 = 10 \).

There are \( 6 + 4 = 10 \) kids playing at the park in total. ✅

Let's find out how many oranges are left! 🍊

• Step 1: Start with the total number of oranges: 10.
• Step 2: You and your sister ate 3 oranges. When you eat them, they are gone, so you subtract.
• Step 3: Write the subtraction problem: \( 10 - 3 \)
• Step 4: Count back 3 from 10: 9, 8, 7.
• Step 5: The answer is 7.

There are \( 10 - 3 = 7 \) oranges left for tomorrow. ✅

Let's find the missing number! We need to figure out what to add to 7 to get 15. 📌

• Strategy 1: Count On
• Step 1: Start at 7.
• Step 2: Count up until you reach 15, keeping track of how many numbers you counted:
• 7... (1)8, (2)9, (3)10, (4)11, (5)12, (6)13, (7)14, (8)15.
• You counted 8 numbers.
• Strategy 2: Subtraction Fact Family
• Step 1: We know that addition and subtraction are related. If \( 7 + \text{_} = 15 \), then \( 15 - 7 = \text{_} \).
• Step 2: Subtract 7 from 15: \( 15 - 7 = 8 \).

The missing number is 8. So, \( 7 + 8 = 15 \). ✅
