Grade 9 weekly pack, week 40 of 2026

Five worksheets for Monday to Friday, 15 questions each, with answer keys. Print one day at a time or the whole week with a cover page.

The five days

Monday

Mathematics: Coordinate geometry

15 questions

  1. Find only the x-coordinate of the midpoint of (16, 9) and (-16, -9).
  2. Reflect (16, 1) in x = -3. What is the new x-coordinate?

Tuesday

Reading & writing: Creative writing

15 questions

  1. Which question concerns the argument's reasoning rather than its tone?
  2. Which phrase clearly introduces a counterargument?

Wednesday

Biology: Genetics & inheritance

15 questions

  1. In pea plants, the allele for round seeds (R) is dominant over the allele for wrinkled seeds (r). Two plants, RR × RR, are crossed. What percentage of the offspring are expected to show round seeds?
  2. A DNA template strand reads ACAGCTC. Which mRNA sequence is transcribed from it, read base by base in the same order?

Thursday

Mathematics: Powers & roots

15 questions

  1. Find n: 2^8 × 2^10 = 2^n.
  2. Find n: 20^4 ÷ 20^11 = 20^n.

Friday

Review of the week

15 questions · Coordinate geometry, Creative writing, Genetics & inheritance, Powers & roots

  1. In the simple Aa × Aa inheritance model with independent outcomes, the probability of aa is 1/4. Among 360 offspring, find the expected aa count, not a guaranteed outcome. Round to 3 decimal places if needed.
  2. A fictional diploid organism has 50 chromosomes in a normal somatic nucleus. In the standard meiosis model, how many chromosomes are in a haploid gamete? Round to 3 decimal places if needed.

Lesson of the week

Coordinate geometry

From the study guide Midpoint coordinates

Study guide for Grades 8 to 10: 2 worked examples and 2 practice questions. Average the x-coordinates separately from the y-coordinates.

  • M = ((x₁ + x₂)/2, (y₁ + y₂)/2)
  • Average the x-coordinates separately from the y-coordinates.
  • Example: Find only the x-coordinate of the midpoint of (19, -12) and (-12, 11). Answer: 3.5.
