Missouri Learning & Developmental Standards: 4th Grade

How to use this document

Use this as a planning reference for 4th grade learning. It lists specific skills, strategies, and behavioral indicators that go beyond general standards descriptions.

Content strategy: Keep explanations short and clear, but require deeper reasoning. Build in discussion, evidence, and multi-step thinking.

Mathematics

Critical areas: multi-digit operations, fraction equivalence/operations, geometric properties.

Domain	Focus (skills and strategies)
Number Sense & Base Ten (4.NBT)	Read and write multi-digit numbers in standard, word, and expanded form. Compare multi-digit numbers using >, =, < symbols. Add/subtract fluently with the standard algorithm by end of year. Multiply 4-digit by 1-digit and 2-digit by 2-digit using place value strategies (area models, partial products). Divide up to 4-digit dividends by 1-digit divisors using strategies like partial quotients.
Fractions (4.NF)	Compare fractions with different numerators/denominators using common denominators or benchmarks. Decompose fractions into sums with the same denominator in more than one way. Add and subtract mixed numbers with like denominators. Solve word problems involving multiplication of a fraction by a whole number. Use decimal notation for fractions with denominators 10 or 100.
Measurement & Data (4.MD)	Convert within a measurement system (km, m, cm; kg, g; lb, oz; L, mL; hr, min, sec). Apply area and perimeter formulas for rectangles in real-world problems. Create line plots using fractional units (1/2, 1/4, 1/8).

English Language Arts (ELA)

Critical areas: text structure, integrating sources, complex sentences.

Strand	Focus (skills and strategies)
Reading Literature (4.R.1 - 4.R.4)	Describe characters, settings, or events in depth using text evidence. Explain differences between poems, drama, and prose and refer to structural elements. Compare and contrast themes and patterns across stories from different cultures.
Reading Informational (4.R.5 - 4.R.9)	Interpret information from charts, graphs, diagrams, time lines, and digital media. Compare firsthand and secondhand accounts of the same event. Integrate information from two texts on the same topic.
Writing (4.W)	Write opinion pieces with reasons supported by facts and details. Write informative texts with grouped information, headings, and visuals when useful. Write narratives with dialogue, description, and character response. Research using print and digital sources; take notes and list sources.
Language (4.L)	Use relative pronouns and relative adverbs correctly. Form and use prepositional phrases. Write complete sentences and correct fragments/run-ons. Use Greek/Latin roots and affixes to determine word meaning. Distinguish literal vs non-literal language (similes, metaphors).

Social Studies: Missouri History Deep Dive

Critical focus: Missouri in national expansion and conflict.

Theme	Focus (knowledge and understanding)
Indigenous Peoples of Missouri	Identify and describe the Osage, Missouria, Illini, Otoe, Ioway, Quapaw, and Chickasaw. Understand the impact of European settlement on these tribes.
Expansion & Conflict	Louisiana Purchase and St. Louis as the Gateway to the West. Lewis & Clark roles: Meriwether Lewis, William Clark, York, and Sacagawea. Missouri Compromise (1820): Missouri as slave state, Maine as free state. Dred Scott Decision: basic premise and St. Louis origins. Civil War in Missouri: Border State tensions and key events (Wilson's Creek, Pilot Knob, General Order No. 11).

Science (Expanded)

Critical areas: engineering design and systems thinking.

Strand	Focus (investigations and skills)
Engineering Design (4.ETS1)	Define a simple design problem with criteria and constraints. Generate and compare multiple solutions based on how well they meet criteria.
Specific Investigations	Erosion: model how vegetation affects soil erosion rates. Circuits: build series and parallel circuits to light a bulb or run a motor. Eye model: show how light entering the eye allows objects to be seen.

Part 2: Developmental Deep Dive

Phase: The Age of Industry & Structure

These developmental expectations highlight how 4th graders think, plan, and navigate peer dynamics. Use them to guide supports at home and school.

1. Executive Functioning: The "Output" Challenge

Time blindness

Many 4th graders underestimate how long tasks take.

Strategy: Use analog clocks or visual timers so they can see time passing.

Multi-step planning

They often need help breaking large tasks into chunks with checkpoints.

Organization

The "black hole" backpack is common. Weekly clean-out routines help.

2. Social-Emotional: The "Social Comparison" Shift

Spotlight effect

Embarrassment feels bigger; students feel like everyone is watching.

Clique formation

Friendships shift toward shared interests and values; subtle exclusion appears.

Moral nuance

They begin to question authority and want to understand the logic behind rules.

3. Red Flags (When to Intervene)

Academic

Cannot recall multiplication facts (0-10) by mid-year.
Cannot write a complete sentence with a capital and period.
Consistently avoids reading.

Social

Withdraws from activities they used to enjoy.
Physical symptoms on school mornings (stomach aches).
Cannot resolve minor peer conflicts without adult help.

Emotional

Frequent, age-inappropriate tantrums at school.

Summary of key Grade 4 shifts:
Output gap: thinking grows faster than planning and organizing skills.
Social comparison: peer perception matters more and can shape motivation.
Support: regular check-ins and clear routines keep progress steady.
