Solve the addition exercise,
using jumps on the the number line below:
To solve the addition problem using a number line, we'll follow these steps:
Here's the detailed breakdown of each step:
Step 1: We start at 34.
Step 2: We add 40 (the tens from the number 47):
Adding 40 to 34 gives us .
Step 3: We add 7 (the units from the number 47):
Adding 7 to 74 gives us .
Therefore, the sum of is .
Thus, the final answer is , which corresponds to choice 3 in the given multiple-choice options.
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Breaking numbers into tens and ones makes jumps easier to visualize and count! Large jumps like +47 are hard to track accurately, but +40 and +7 are manageable steps.
You can do that since addition is commutative! However, adding tens first is usually easier because larger jumps are simpler when you start from round numbers.
Start at your first number (34), then make equal-sized jumps. For +40, make 4 jumps of 10 each. For +7, make 7 single jumps or count forward 7 spaces.
Yes! This decomposition strategy works for all addition. Break the second number into place values (hundreds, tens, ones) and add each part step by step.
You can still use the jumping strategy mentally! Count the jumps even if specific numbers aren't marked. The important part is understanding the size of each jump.
