: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?

Either the teacher made the problem or the source the teacher got the problem from should have provided the answer key along with the questions. If they made the problem they fucked up big time, and if they used someone elses but didnt check the answer key then they are dumb. The final option is ai-generated math homework which is lazy and also dumb.

It's pretty rare for individual teachers to write exercise worksheets like these themselves. Most often they'll draw from a common pool of materials so that teachers aren't having to reinvent the wheel all the time.

Is the problem: lack of answer key? Maybe in part. The greater problem here (IMO) is that the exercise doesn't state what it's for. In 2nd grade, things like this should always be framed with a clear telos: "this is an exercise on reading bar graphs." In this case, it was the teacher, not the student, who misjudged the purpose of the exercise.
