Being in complete agreement with Dan Meyer on the term “Write an expression” I take exception to the vague instruction “Write a number sentence”.
Multiple choice question – Which of the following is a number sentence?
a) 3 + 2 = 5
b) three + two = five
c) three and two makes five
d) 2 + don’t know = 7
e) seven is 5 more than 2
f) they gave him 20 years
g) Mary gave three of her sweets to Jane and was left with 5
h) none of these, although they all have a verb
