CCSS.Math.Content.4.NBT.B

CCSS.Math.Content.4.NBT.B is a cluster heading. These are the individual standards under it.

• CCSS.Math.Content.4.NBT.B.4

  Fluently add and subtract multi-digit whole numbers using the standard algorithm.

• CCSS.Math.Content.4.NBT.B.5

  Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the prop...

• CCSS.Math.Content.4.NBT.B.6

  Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of oper...

01

What Students Need to Do

Students add and subtract whole numbers accurately with written algorithms. They multiply multi-digit numbers and divide four-digit numbers by one-digit divisors, explaining how each step uses place value.

02

What Mastery Looks Like

Students accurately solve multi-digit addition, subtraction, multiplication, and division problems. They show organized work, explain regrouping or partial products, and use estimation to check whether answers make sense.

03

Common Misconceptions

Students may line up digits by the left edge instead of by place value, or regroup without recording the changed value. They may omit zero placeholders in multiplication or write 43 for 19 ÷ 4 instead of 4 remainder 3.

How to Assess It

Exit ticket: solve 6,482 + 3,759, 7,004 − 2,867, 36 × 24, and 2,365 ÷ 5. Choose one and label how place value supports a step.

1. 01

   Use base-ten blocks or place-value disks to model 324 × 3, then connect each regrouping move to the written algorithm.

2. 02

   Ask students to compare partial products and the standard algorithm for 36 × 24, then write why both give the same product.

3. 03

   Play an operation-card game where pairs draw number cards, solve an assigned operation, and check each other’s work with estimation.

4. 04

   A school has 2,468 pencils packed equally into 6 bins; find pencils per bin and leftovers, then explain the result.

• CCSS.Math.Content.1.NBT.C

  Use place value understanding and properties of operations to add and subtract.

• CCSS.Math.Content.4.NBT.A

  Generalize place value understanding for multi-digit whole numbers.

• CCSS.Math.Content.2.NBT.B

  Use place value understanding and properties of operations to add and subtract.

• CCSS.Math.Content.3.NBT.A

  The 3rd Grade version of this standard.
