A K-8 Sample of Singapore Math Questions
Grade 1
Use the [Singapore] model method to show that (a) 2 + 3 = 5, (b) 9 – 4 = 5.
Grade 2
Use a model to show that 3 × 6 = 6 × 3.
Grade 3
Use a model to show that ½ × ⅘ = ⅖.
Grade 4
Use a model to show that 2 ÷ ⅖ = 5.
Grade 5
Use the model method to evaluate the value of 3½ × 4⅚.
Grade 6
Use a model diagram to show that the infinite series converges to a finite number.
½ + ¼ + ⅛ + ⅟₁₆ + ... = 1
Grade 7
Use a model to show that (2x)² is not equal to 2x².
Grade 8
Use a model method to solve these equations.

An Evolution of Grade 5/6 Singapore Math Word Problems
Teaching Math in 1970 (Traditional Math)
Mr. Yan has three cows and eight chickens. How many legs are there altogether? [Ask a next-door neighbor for the answer.]
Teaching Math in 1980 (Model Method)
Mr. Yan has twice as many cows as chickens. If there are 64 legs in all, how many cows are there? [Ask a neighborhood school teacher for the answer.]
Teaching Math in 2000 (Problem Solving)
Mr. Yan has cows and chickens. If there are altogether 28 legs, how many chickens and how many cows are there? [Ask a full-time tutor for the answer.]
Teaching Math in 2010 (Challenging)
Mr. Yan has almost twice as many chickens as cows. The total number of legs and heads is 184. How many cows are there? [Answer a math coach, or a volunteer from the Ask Dr. Math Website.]
What the most-disliked subject means for the average or above-average Singapore student (in spite of TIMSS):
K1-K2: Math is a lore.
