Using Make Ten to Add

: "The sun is so warm, it's perfect for this walk!" : "And look at these mushrooms!" Mr. Squeaks and Imani are out for a walk when Mr. Squeaks sees something that catches his eye. While exploring the mushrooms he suddenly realizes that he's lost! : (concerned, then lost) "Imani? IMANI!" Mr. Squeaks needs a strategy to help. He can add the different mushrooms to count his way back! Let's learn about "using make ten to add" to help Mr. Squeaks. There are different strategies that you can use to solve addition equations. One is to use 'make ten' when adding. You may know about the ten frame... and that when we fill all of the boxes, we have ten. Let's use the ten frame to add using 'make ten'! Mr. Squeaks first passed twenty-six red mushrooms and then fifteen purple mushrooms. How many mushrooms has he passed in total? We can start by creating an equation, or number sentence. Which is twenty-six plus fifteen. Next, take the smaller addend, we can break it apart to make smaller numbers. We can take fifteen and make it a ten and a five. Now we have twenty-six plus ten plus five, which may be easier to add. Then, solve using the ten frame. While there are different ways to add, in this video we will add by tens and count on. What is twenty-six plus ten? (...) Thirty-six. Now, we can add thirty-six plus five (...) which is forty-one. That means twenty-six plus fifteen equals forty-one. : "Okay, I've passed forty-one mushrooms, I can't be far." : (confused) "Wait, I didn't pass green mushrooms yet..." Mr. Squeaks just saw thirty-two green mushrooms and then twelve brown ones. How many mushrooms did he pass? Start by creating an equation. We can create thirty-two plus twelve. Next, take the smaller addend and break it apart to make it smaller. Here we can take twelve and make a ten and a two. Now we have thirty-two plus ten plus two. Then, solve using the ten frame. What is thirty-two plus ten? (...) forty-two! What is forty-two plus two? (...) forty-four! So, Mr. Squeaks has passed forty-four mushrooms. : "I MUST be close now!." : (incredulous and confused) "MORE MUSHROOMS?" We can use 'make ten' to help Mr. Squeaks one last time. Mr. Squeaks saw forty-seven spotted mushrooms and seventeen small ones. How many mushrooms should he add? Remember to start by creating an equation. We can create forty-seven plus seventeen. Next, take the smaller addend and break it apart to make it even smaller. Here we can take seventeen and make one ten and seven ones. Now we have forty-seven plus ten plus seven. What is forty-seven plus ten? (...) Fifty-seven What is fifty-seven plus seven? (...) Sixty-four. Mr. Squeaks needs to add sixty-four mushrooms to his list. Let's review! When using 'make ten' to add... start by creating an equation. Next, take the smaller addend and break it apart to make smaller addends. Don't forget to fill the ten frame with the smaller addends! Then, solve using the new equation. In this video we added by tens and counted on. Now, I wonder how Mr. Squeaks is doing... : "IMANI! I missed you! I thought I was lost forever!" : (worried) "I-imani? That's you, right?" : "Surprise! It's me!"
