Work through the list without notes. If you cannot do a statement, follow the pointer, then come back. Guide = the study guide; Practice = the practice questions.
Understanding
- I can state that an expression is evaluated to a single value (Guide: Expressions and how they are evaluated)
- I can explain what a MOD b means in terms of whole copies and a remainder (Guide: MOD from first principles; Practice: Question 1)
- I can state that MOD shares precedence with * and / and that equal precedence goes left to right (Guide: Expressions and how they are evaluated; Practice: Questions 2 and 6)
- I can explain why a MOD b is always between 0 and b - 1 (Guide: MOD from first principles; Practice: Question 4)
Skills
- I can evaluate an expression that mixes + - * / and MOD (Guide: Worked example 1; Practice: Questions 2 and 9)
- I can write an expression that tests for even, odd or divisible by d (Guide: MOD from first principles; Practice: Question 3)
- I can extract the last digit of a number and remove it (Guide: Worked example 2, Part C; Practice: Question 5)
- I can convert a number of minutes or seconds into whole units plus a remainder (Guide: Worked example 2, Part A; Practice: Question 8)
- I can wrap a value onto a clock with MOD (Guide: Worked example 2, Part B; Practice: Question 4)
Reasoning
- I can identify the precedence error that produced a wrong answer (Guide: Common misconceptions; Practice: Question 9)
- I can check a MOD result by multiplying back and adding the remainder (Guide: Worked example 2; Practice: Question 8)
- I can decide which of several expressions gives a required value (Guide: Worked example 1; Practice: Question 7)
