Where students go wrong

The most common mistake on each standard, and what to do about it, from the teacher pages in the Checkpoint 1 intervention.

3.NS.1

Writing what you hear, place by place

What it looks like: "Four thousand seventy" written as 4,000,70 or 40,070. The student writes each spoken chunk as its own number and joins them, so the answer has too many digits and the zero lands in the wrong place.
What to do: Draw the four boxes for thousands, hundreds, tens and ones FIRST, then fill them. An empty box has to take a zero; it cannot be skipped.

3.NS.6

Looking at the wrong digit

What it looks like: 274 rounded to the nearest ten comes back as 300. The student rounds by the biggest digit they can see, or by the first one, instead of the one to the right of the place being rounded to.
What to do: Underline the place you are rounding TO, then put your finger on the digit immediately right of it. That finger decides, and nothing else on the page does.

3.CA.1

Subtracting the smaller digit from the larger, column by column

What it looks like: 8,004 − 3,567 comes back as 5,563: in every column the student takes whichever digit is smaller from whichever is larger, so no regrouping happens anywhere. Each digit looks reasonable on its own.
What to do: Estimate first — 8,000 minus about 3,600 is about 4,400 — so a 5 in front is wrong before any column is worked.

3.CA.2

Stopping after the first step

What it looks like: A two-step problem answered with the subtotal. The arithmetic is right and the answer is a number that genuinely appears in the working, so it does not look wrong at a glance.
What to do: Underline the question sentence before computing anything, then check the final answer against that sentence rather than against your own work.

3.M.4

Counting coins as objects rather than values

What it looks like: Three quarters reported as 3¢, or a mixed handful counted as its number of coins. The count is right and the value is not.
What to do: Write the value on each coin before adding anything. A quarter is not one thing, it is twenty-five things.
