Question

A student club set a goal of donating 50 blankets to a local shelter. Two classes have participated so far. Ms. Carter’s class gathered 18 blankets and Mr. Moriarti’s class gathered 23 blankets. How many more blankets are needed to reach the goal of 50 blankets
What type of problem is this? How can you tell?

a part-whole problem because Ms. Carter’s class only gathered part of the number of blankets Mr. Moriarti’s class gathered

a part-whole problem because the unknown number of blankets that are still needed is part of the whole goal of 50 blankets

a comparison problem because the number of blankets gathered is compared to the number of blankets still needed

a comparison problem because the number of blankets Ms. Carter’s class gathered is compared to the number of blankets Mr. Moriarti’s class gathered

Answer 1

The correct answer is that this is a part whole problem because the unknown number of blankets that are still needed is part of the whole goal of 50 blankets.
the whole value should be 50 blankets. Part of these blankets have already been collected, thats (18 +23) 41 blankets.
we have been given the whole that's 50 and we have been given the part thats 41 in total. we still have to find the other part that should be included to make the whole number of blankets. We can find the unknown number by subtracting the part given (41) from the whole (50) and the unknown is then 9 blankets.
Therefore this is a part whole problem to find out the missing part.
