Week 1

Operations and Algebraic Thinking & Number and Operations in Base Ten

Interpret multiplication equations as comparisons and write comparison statements for 12 given pairs of numbers.
Solve two-step word problems using all four operations and label each step with the operation chosen.
Read and write whole numbers to 1,000,000 in standard, expanded, and word form without error.
Round multi-digit whole numbers to any place value and justify each rounding with a number-line sketch.

Week 2

Identify factor pairs for all numbers 1 through 50 and classify each as prime or composite.
Generate and extend numeric and shape patterns, then state the rule in a complete sentence.
Distinguish multiplicative comparison language from additive comparison language in 15 mixed prompts.
Solve multi-step problems involving remainders and explain what the remainder means in context.

A factor-pair chart for 1-50 plus a written log of 10 pattern problems showing the rule and the next three terms.

Week 3

Fluently multiply up to four-digit by one-digit numbers using the standard algorithm and check with estimation.
Multiply two two-digit numbers using area models and connect each partial product to the algorithm.
Divide up to four-digit dividends by one-digit divisors, interpreting remainders in three different ways.
Explain place-value shifts when multiplying or dividing by 10, 100, and 1,000.

A timed set of 25 multiplication and division computations at 90% accuracy or better, with estimation checks shown for each.

Week 4

Add and subtract multi-digit whole numbers using the standard algorithm and verify with inverse operations.
Build equivalent fractions using visual models and justify equivalence with multiplication or division.
Compare two fractions with unlike denominators using benchmark fractions and common denominators.
Decompose a fraction into a sum of unit fractions in more than one way.

A one-page reference sheet of fraction equivalence and comparison strategies, plus 15 worked comparison problems using it.

Week 5

Add and subtract fractions and mixed numbers with like denominators and simplify results.
Multiply a whole number by a fraction and model the product with a number line or area diagram.
Solve word problems involving addition and subtraction of fractions by first identifying the whole.
Convert between improper fractions and mixed numbers in both directions with accuracy.

A 15-problem fraction operations quiz scored at 80% or higher, with a corrected rewrite of any problem missed.

Week 6

Express a fraction with denominator 10 as an equivalent fraction with denominator 100 and add the pair.
Convert measurement units within one system and record the results in a two-column table.
Solve elapsed-time problems to the nearest minute using a number line.
Apply area and perimeter formulas to real-world rectangular figures and distinguish the two.

A measurement-and-fraction word-problem set of 12 problems, fully worked with unit labels on every answer.

Week 7

Draw and interpret line plots with fractional data and answer questions about the data set.
Measure angles with a protractor and classify them as acute, right, or obtuse.
Identify and draw points, lines, line segments, rays, and angles, and name them correctly.
Classify two-dimensional figures by parallel and perpendicular sides and by angle type.

A hand-drawn geometry and data portfolio: one line plot with fractional data, five measured angles, and a labeled figure classification chart.

Week 8

Complete a full-length mixed-domain practice set under timed conditions.
Categorize every error by domain and by error type (concept, computation, or misread).
Re-teach the two weakest skills using worked examples and re-test them.
Build a one-page formula and vocabulary sheet covering all five domains.

A timed 40-question mixed practice test with an error analysis table and a scored re-test of the two weakest skills at 85% or better.

Week 2: Score 80% or higher on a self-made 15-question operations and algebraic thinking quiz, including at least three multi-step word problems.

Week 4: Complete 20 multi-digit multiplication and division problems with 85% accuracy and show an estimation check for each.

Week 6: Score 80% or higher on a 15-question fraction and measurement quiz, with unit labels present on all measurement answers.

Week 8: Score 75% or higher on the timed 40-question mixed practice test and show measurable improvement on the two re-tested weak skills.
