Operations and Algebraic Thinking (4.OA)

Use the four operations with whole numbers to solve problems

Interpret multiplication as a comparison: Students must understand that multiplication can be used to compare quantities, such as understanding that 4 times as many means multiplying by 4.

• Common mistakes: Misinterpreting the context, thinking of a multiplication equation as addition rather than a multiplicative comparison 

For example: interpreting 35 = 5 × 7 as 35 = 5 + 7.

• How to correct this: Use contextual problems and visual aids like arrays or drawings to illustrate comparisons,

For example: “If one apple costs $7 and you buy 5 apples, the total cost is 5 times 7.”

Solve multistep word problems: Students must break down a complex problem into simpler steps and apply appropriate operations in sequence.

• Common mistakes in solving multistep word problems: Missing steps or applying incorrect operations.

For example, a student adds all the numbers they see without considering the problem’s context.

• How to correct this: Teach students to break down the problem into simpler steps.

For example, use diagrams and checklists to address all parts of the problem systematically.

Gain familiarity with factors and multiples

Find factor pairs for numbers 1-100: Students should know how to identify pairs of numbers that, when multiplied together, equal the original number.

• Common mistakes in identifying factors and multiples: Students may confuse factors with multiples.

For example, listing 24 as a factor of 12.

• How to correct this: Reinforce with exercises focusing on the reciprocal nature of factors and multiples.

For example, use factor trees and Venn diagrams to segregate and understand factors and multiples visually.

Generate and analyze patterns

Create and analyze number or shape patterns: Students should be able to identify rules governing patterns and extend them accurately.

• Common mistakes in generating and analyzing patterns: Students may fail to recognize the pattern’s rule

For example, missing that the pattern increases by 3 each step.

• How to correct this: Encourage students to articulate the rule governing the pattern and validate it through multiple examples.

For example, use math manipulatives and visual aids to deliberate patterns.

Number and Operations in Base Ten (4.NBT)

Generalize place value understanding for multi-digit whole numbers

Recognize that a digit in one place represents ten times what it represents in the place to its right: Students need to comprehend the hierarchical structure of place value and its impact on the digit’s value.

• Common mistakes in understanding place value: Misplacing digits

For example, thinking in 530, the digit 3 represents 30 tens instead of 3.

• How to correct this: Practice with exercises that move digits within different place values.

For example, use a place value chart and base ten blocks to visualize the concept.

Read, write, and compare multi-digit numbers: Students should be proficient in expressing numbers in standard form, expanded form, and word form, as well as comparing their values.

• Common mistakes in reading, writing, and comparing numbers: Confusion with ordering and comparing more extensive digits.

For example, misinterpreting 5,431 as smaller than 5,143.

• How to correct this: Consistent practice with expanded, word, and standard forms.

For example, use number lines and comparative exercises to reinforce understanding of orders and magnitudes.

Use place value understanding to round multi-digit whole numbers to any place: Students should be able to apply their understanding of place value to round multi-digit whole numbers to a specified place value.

• Common mistakes in rounding multi-digit whole numbers: Incorrect identification of the target place value when rounding.

For example, rounding 456 to the nearest hundred as 500 instead of 400.

• How to correct this:  Provide real-world examples and scenarios for practical application of rounding.

For example, provide a list of snacks from the grocery store and a budget of $20. Students practice rounding to the nearest dollar to see if they have enough money for everything on the list.

• How to correct this: Encourage the use of visual fraction models to visually represent the fractions being added or subtracted within the context of the word problem.

Apply and extend understanding of operations on whole numbers

Apply and extend previous understandings of multiplication to multiply a fraction by a whole number: Students should grasp the concept of scaling a fraction by a whole number to determine a specified fraction of the whole.

• Common mistakes: Misinterpreting the operation as simply multiplying the numerator by the whole number without adjusting the denominator.

• How to correct this: Reinforce the concept of scaling and visual representation when multiplying a fraction by a whole number. Encourage students to view the whole number as a fraction with a denominator of 1 to aid in understanding the fraction of the whole being calculated.

For example, when solving the problem \frac{2}{3} x 4, prompt students to think of the whole number 4 as \frac{4}{1} and proceed with the multiplication: (2 x 4)/(3 x 1) = \frac{8}{3}. Encourage students to simplify the resulting fraction.

Understand decimal notation for fractions, and compare decimal fractions

Express fractions with denominators 10 and 100 as decimals: Students should convert fractions with denominators of 10 or 100 into decimal form – tenths or hundredths.

• Common mistakes in decimal notation: Misplacing decimal points when converting fractions

For example, writing 0.75 as 0.075.

• How to correct this: Use decimal grids and place value charts to visualize and correctly place decimal points.

Compare decimals to hundredths: Students must compare decimal values using reasoning through place values.

• Common mistakes in comparing decimals: Confusing decimal place values.

For example, assuming 0.6 is less than 0.56 since 6 < 56.
