Grade 1 Mathematics, Chapter 10: Review: Place Value, Measurement, and Problem Solving
Student lessons | Daily practice | Teacher guide | Grade 1 learning path
Five original guided lessons for a developing Grade 1 course. Read or demonstrate each lesson before practice. An adult should adjust pace for readiness and safety.
Day 1: Regroup and Explain
Learn: Two-digit numbers have tens and ones. Adding may regroup ten ones into another ten. Record an equation and check it using counters or a number line.
Worked example: For 38 + 7, add two to reach 40 and the remaining five to reach 45. The amount does not change when seven is split into two and five.
Guided check: Explain an idea aloud, then complete the matching four practice questions.
Day 2: Measure and Compare
Learn: Measure an object by placing equal units end to end with no gaps or overlaps. State the unit. To compare lengths, use identical units or a common ruler scale.
Worked example: A strip spans from the 2 cm mark to the 11 cm mark. Its length is 11 – 2 = 9 cm. Merely naming the far endpoint is wrong.
Guided check: Explain an idea aloud, then complete the matching four practice questions.
Day 3: Read and Organize Data
Learn: Read a picture or bar graph’s labels and key before counting. More symbols do not always mean more items unless the key says one symbol equals one item.
Worked example: Fictional book votes: mysteries 7, animals 5, space 8. Total votes are 20. Space exceeds animals by 3.
Guided check: Explain an idea aloud, then complete the matching four practice questions.
Day 4: Two-Step Stories
Learn: Some stories require two operations. Draw the changes in sequence, then write the equation and label its unit. Estimate whether the answer makes sense.
Worked example: A basket holds 24 apples. Six are added and nine removed. The final count is 24 + 6 – 9 = 21 apples.
Guided check: Explain an idea aloud, then complete the matching four practice questions.
Day 5: Independent Chapter Check
Learn: Use counters or drawing paper, but do not receive answer hints. Explain one computation, record a unit in measurement, and cite numbers used in the data question.
Worked example: Fictional lengths: blue 14 cm, green 9 cm. Fictional votes: apples 6, oranges 4.
Guided check: Explain an idea aloud, then complete the matching four practice questions.
Curriculum status: This chapter completes a chapter-number sequence but not full-year certification. Full textbooks, dedicated fillable PDFs, robust assessments, accessibility review, and verified Alabama standards alignment remain outstanding. Scripture Study is separate from academic standards.
