Module 3 Lesson 11

Objective Count the total value of ones, tens, and hundreds with place value disks.

Warm-up What number is showing? 11! Say it the unit form way 1 ten 1 one

Warm-up 1 ten 2 ones 1 ten 3 ones 1 ten 4 ones 1 ten 5 ones Keep Counting the unit form way 1 ten 2 ones 1 ten 3 ones 1 ten 4 ones 1 ten 5 ones

Warm-up This time say each number 2 ways. First the unit form way, then just as ones. Let’s do one together. My turn: 2 tens 5 ones is 25 ones. Your turn 2 tens 5 ones is 25 ones. Continue to count by tens to 55 3 tens 5 ones is 35 ones 4 tens 5 ones is 45 ones 5 tens 5 ones is 55 ones Now say the ones first, then the unit form. Lets count to 61. 56 ones is 5 tens 6 ones 57 ones is 5 tens 7 ones 58 ones is 5 tens 8 ones 59 ones is 5 tens 9 ones 60 ones is 6 tens 61 ones is 6 tens 1 ones

Sprints Put your name and number at the top of the page Sprint A On your mark, get set, THINK Lets check your work Write the number you got correct up top Sprint B What was your improvement?

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? Bundle or boxes Go ahead and draw. (2 minutes) Go ahead and solve the problem What is the answer in a complete statement? 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 Now show me the same number with your disks. Whisper the number first in unit form, then in standard form to your partner. Continue practicing Talk with your partner about the difference between modeling your numbers with blocks and modeling with place value disks. 13 103 129 130 230 203 199 200

NOW YOU DO IT! DEBRIEF and then complete EXIT TICKET Practice the skills we just learned in your problem sets. Directions A-E: Model the numbers on your place value chart using the fewest number of blocks or disks possible. Partner A use base ten blocks Partner B use place value disks Whisper each number in unit and standard form. Directions F-O: Model the numbers on your place value chart using the fewest number of disks possible. Partner A and B alternate using place value disks DEBRIEF and then complete EXIT TICKET
