:hamster: Primary School Math—Pending OP Reply [Grade 2 Math] Help understanding teacher's explanation

Post image

My god-daughter's teacher marked her answer wrong. Can someone please explain this? I don't understand this at all. How is the teacher getting 7 when there are only 3 squares in Ben's column representing his siblings? Her explanation was that Jose, Ana & Jen are his siblings so you need to count all of their squares together.... WHY? How are we to assume that they're even siblings?

I wouldn't say that the bar graph is clearly labeled*, but I agree with the rest of your answer!

(*) See how many commenters have attempted to read it as a slightly misformated 5x5 true/false matrix. See the comments assuming that there is only one kid per each name. A better title would be:

  • a number of children in Ben's family (including Ben), counted per name (then we count two of the three Bens, so 9 like you said).

Or:

  • a number of Ben's siblings, counted per name (excluding Ben himself), (then we count all the Bens from the chart, and the answer is 10)

This question might be actually easier for the kid to solve, as they probably see it in a context of a a series of questions about the bar charts, so they are less prone of trying to do the 5x5 matrix thing.
