a farmer was planting green beansin fourteen rows of fifteen. the area model is how he thoughtabout the number of plants he got. first, he multiplied ten by tenand wrote one hundred with his pad and pen. then he multiplied ten by five;there were fifty more plants coming alive. then ten times four equals forty,and just the bottom corner was empty.
How To Add Fractions Using Area Models, so, he multiplied five by fourand ended up with twenty more. split up the place values in multiplication.multiply the tens to get the foundation. then the other place values get multiplied.add the partial products up, and check your work twice. then the farmer planted black beans
in twenty-two rows of fifteen.to find out how many plants he had, he drew the area model on his sketch pad.he did twenty times ten and wrote two hundred down; then ten times two, and twenty’s what he found. twenty times five was one hundred, and then, five times two equaled ten.he added two hundred, one hundred, twenty, and ten; the sum was three [hundred] thirty; he checked it again. so, there were three hundred thirty blackbeans in twenty-two rows of fifteen.split up the place values in multiplication. multiply the tens to get the foundation.then the other place values get multiplied.
add the partial products up, and check yourwork twice.
