An original grade-labeled starting unit in five academic and Scripture subjects. Each subject contains direct teaching and ten exercises. This is a first unit, not a completed chapter sequence or full annual textbook. Any child may be ready for a higher-grade challenge in one subject while working at another level elsewhere.
Instructions: Read the explanation and passage, if provided. Complete the ten numbered tasks on paper or copy into a document. Explain how you reached an answer. Parents check learning separately and privately.
Mathematics: Functions, linear equations and systems
Learn: A linear function can be written y=mx+b, where m is slope and b the vertical intercept. The slope between (2,5) and (6,13) is (13-5)/(6-2)=2. Two linear equations form a system, and a solution satisfies both.
- Compute slope between (2,5) and (6,13).
- Find y-intercept of y=3x-7.
- Evaluate y=-2x+5 for x=-1.
- Solve 5(x-2)=3x+8.
- Solve y=x+2 and y=2x-1 simultaneously.
- Write line equation with slope 4 and y-intercept 3.
- Evaluate 2^3 x 2^4.
- Write 0.00056 in scientific notation.
- Find hypotenuse of right triangle with legs 5 and 12.
- Advanced: prove a vertical line fails the vertical line test for y as a function of x.
Independent check: Explain one solution with evidence, then review errors and try an unfamiliar problem. Advanced work is available by readiness, not birthday.
English Language Arts: Evidence-driven analytical writing
Original reading: Original passages: A: ‘The archive catalog includes 43 dated images from the period. It also warns that the collection excludes private photographs.’ B: ‘The available archive is a complete account of the community’s experience.’
Learn: Historical or analytical claims must be proportionate to evidence. A limited collection cannot establish complete coverage; source selection and absent perspectives matter. Advanced essays need a thesis, precise evidence and qualifications.
- State the verifiable claim in A.
- Identify the overclaim in B.
- Explain the limitation identified in A.
- Write one defensible conclusion using A.
- Write a three-sentence summary without exaggeration.
- Identify an alternative source that could broaden representation.
- Analyze the author’s use of the word complete.
- Draft a thesis about archival limitations.
- Write a 250-word evidence-based analysis.
- Advanced: include counterargument and respond without a straw man.
Independent check: Explain one solution with evidence, then review errors and try an unfamiliar problem. Advanced work is available by readiness, not birthday.
Science: Scientific models, forces and energy
Learn: Models represent aspects of reality while omitting others. In Newtonian mechanics, force relates to changes in motion. Kinetic energy depends on mass and speed. Experimental evidence and unit consistency matter for evaluating explanations.
- Define scientific model.
- Give one strength of a model.
- Give one limitation of a model.
- Compute speed for 120 m in 20 seconds.
- State the SI unit for speed.
- What variable might affect a rolling object’s stopping distance?
- Design a controlled test of that factor.
- Explain why repeating trials matters.
- Compare a measured value to a model prediction in a hypothetical example.
- Advanced: explain why a correlation cannot by itself establish a mechanism.
Independent check: Explain one solution with evidence, then review errors and try an unfamiliar problem. Advanced work is available by readiness, not birthday.
History and Social Studies: Primary sources, civil rights and democratic institutions
Learn: Civil rights organizing in Alabama included Montgomery’s 1955–56 bus boycott and the 1965 Selma voting-rights campaign. History requires attention to local participants, legal changes, archival sources and omitted perspectives. Current institutions should be checked using up-to-date sources.
- Locate Montgomery and Selma on a verified map.
- Name an event associated with Montgomery in 1955.
- Name an event associated with Selma in 1965.
- Explain why primary sources matter.
- Describe a limitation of a participant’s single account.
- Find a reliable historical museum or National Park Service source.
- Record the title and institution.
- Explain why a historical interpretation may change with evidence.
- Write a sourced 150-word summary.
- Advanced: compare two credible perspectives and discuss source omissions.
Independent check: Explain one solution with evidence, then review errors and try an unfamiliar problem. Advanced work is available by readiness, not birthday.
Scripture Study: Yahusha’s teaching and literary context
Read in context: Matthew 5:17–20; Matthew 7:24–27
Study note: Read Yahusha’s words in the Sermon on the Mount, including their audiences and surrounding teaching. Matthew 7’s two builders conclude with a contrast between hearing and doing.
- Identify the speaker in Matthew 5.
- Identify what Matthew 5:17 says about Law and Prophets.
- Summarize Matthew 5:18–20.
- Describe the two builders in Matthew 7.
- What distinction does the parable make?
- Identify the passage’s conclusion within the Sermon.
- Distinguish direct text from a later doctrinal reading.
- Write a comparative paragraph with verse citations.
- Explain one responsible application.
- Advanced: analyze the literary relationship between Matthew 5:17–20 and 7:24–27.
Independent check: Explain one solution with evidence, then review errors and try an unfamiliar problem. Advanced work is available by readiness, not birthday.
