Using Multiples of 100 as an Anchor for Addition
Strategy #3: Using Multiples of 100 as an Anchor
Josh had 304 songs on his music player. He downloaded 23 more songs. How many songs are on his music player now?
_ + 23 = ?
Estimate.
300 + 20 = _
Add. Use 300 as an auchor.
300 + 4 + _ =
300 + 27 = _
327 is close to our estimate of 320. So 327 seems like a reasonable answer.

Answer 1

Let's fill in the blanks step by step:

1. Equation using anchors:
   304 + 23 = ?
   (This is the original equation; the first blank for "Using multiples of 100 as an anchor")

2. Estimate:
   300 + 20 = 320
   (This is the estimated sum based on rounding 304 to 300 and 23 to 20)

3. Add using 300 as an anchor:
   300 + 4 + 23 = 327
   (To compute the exact addition, we break it down using 300 as the anchor)

4. Final addition using the original numbers:
   300 + 27 = 327
   (This shows the full addition from the earlier steps)

5. Conclusion about estimation:
   327 is close to our estimate of 320. So 327 seems like a reasonable answer.

So the final filled statement reads as follows:
