One important meaning of subtraction is separating. Children separate a set of objects into two sets to answer questions about how many are left. It is important for children to have many experiences to develop and use language like “how many are left” prior to symbolic work with the operations. From these experiences, children will connect their use of the language to the operation of subtraction and its symbols, such as the subtraction sign.
Today we began our lesson with the book, Born To Be a Butterfly! We then acted out "separating stories" using butterflies.
Five butterflies were fluttering in the breeze. Two flew away! How many were left?
Next, we had fun feeding our caterpillar as we told "separating stories" about a VERY HUNGRY CATERPILLAR!
First we count the correct amount of food to begin our story!
Then we feed our caterpillar!
And we count what is left!
"HANDS-ON" MATH IS SO MUCH FUN!
