what are you wearing hank my new swim trunks ralph makes me feel like i'm on the sandy beaches of hawaii instead of working got you pair too in green thanks hi guys my dad says you're almost done almost we had eight steel beams before that last delivery right hank you know it boss and in that last delivery of beams we got didn't get the number of beams that were just dropped in the bin and need that for my report only know that we have 19 in total that sounds like word problem sure word problem of course and ralph here he knows all about word problems don't you ralph me word problems maybe can help that would be amazing you're real life saver jesse so we know that you started with eight beams and that crane just dropped some more in the bin making it 19 beams altogether when you end up with more than you started with that's addition i'm going to write number sentence since we know we're supposed to add let's start with this now we need to figure out the missing numbers you started with eight beams so let's put the number eight in the first space the next thing we do is ask ourselves what else do we know well we also know there's total of 19 beams in the bin since it's the total that number goes after the equal sign because we don't know how many the crane added we'll put question mark there that stands for the missing number see we've changed our word problem to number sentence now let's solve it one strategy for solving number sentences is to use number family 19 goes at the top because it's the biggest number eight goes in the bottom left corner and question mark goes in the bottom right corner do we have to build that triangle if so we're going to need more beams of course we don't do we nope the triangle just helps us see the number family now i'm gonna write out the four facts that go with this number family okay eight plus question mark equals nineteen question mark plus eight equals nineteen nineteen minus question mark equals eight nineteen minus eight equals question mark hey look at the last number sentence what does it tell us you have nice writing thank you but look 19 minus 8. we can solve that number sentence 19 minus 8 equals eleven the missing number in our number family is eleven and that means the crane delivered eleven beams you're sure about that let's check you started with eight beams this morning and that crane just dropped some more in the bin for total of 19 beams to check your answer you put the missing number in the first number sentence does 8 plus 11 equal 19 yes we have the right answer all right thanks jesse let's get this job done hank ready guys hey dad remember to take off your hard hat nah we're good we don't want to get our hair wet
