Samantha is helping the teacher to organize the pencils in her classroom. She finds 41 yellow pencils and 29 blue pencils. She threw away 12 that were too short. How many pencils are left in all? When you read this problem what do you see? Can you draw something to represent the pencils? I’m only giving you 2 minutes to draw, so would it be wiser to draw bundles, boxes, or all of the pencils? Go ahead and draw. (2 minutes) Go ahead and solve the problem What is the answer in a complete statement? Bundle or boxes 58 pencils are left. What does your drawing show you? Talk with your partner. Students work in partners Each pair will need Base ten blocks (2 hundreds, 9 tens, 9 ones) Place value disks (6 hundreds, 9 tens, 9 ones) 1 place value chart With your blocks show me this number 13 Now show me the same number with your disks.
