Math problems of the week: 2nd grade 1920's math vs. Investigations

I. From the middle of the 2nd grade section of Hamilton's Essentials of Arithmetic (published in 1919), p. 50 [click to enlarge]:

II. From the middle of the 2nd grade (TERC) Investigations curriculum, assigned in early February [click to enlarge]:

III. Extra Credit:
Which involves higher-level thinking: doing nine word problems mixing up the four basic operations of arithmetic, or "making a representation"?

I'm pleased to see that my daughter's 2nd grade curriculum prepared her beautifully for the 1920's curriculum questions. (We're homeschooling with a British program, MEP.) On the other hand, she'd have no idea what the hell they we're talking about with "making a representation."
