If we have 7 blocks and we add a further 7 blocks: How many blocks will we have in total?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The problem provides us with two sets of blocks, each containing 7 blocks. We need to find the total number of blocks after adding them together.
Step 2: Using the formula for addition, add the two sets of blocks: . Performing this addition gives us:
Step 3: Compare this result with the given choices: the correct answer is indeed , which matches choice .
Therefore, the solution to the problem is .
Add fifty units to the number 31.
What is the resulting number?
That would mean you're counting the first 7 blocks three times! We only have two groups: the original 7 blocks plus 7 more blocks. Simply add: 7 + 7 = 14.
Picture two separate piles of blocks. One pile has 7 blocks, the other pile has 7 blocks. When you combine both piles, you get 14 blocks total.
Yes! When adding the same number twice, you can think of it as doubling. So 7 + 7 is the same as 7 × 2 = 14.
Break it down into smaller steps: start with 7, then count up 7 more. Or use your fingers, blocks, or draw pictures to help you visualize the addition.
Try counting backwards: if you start with 14 blocks and take away 7, you should have 7 left. 14 - 7 = 7 ✓ This confirms your addition is right!
