Place Value isfundamental

Research shows: Students who understand Place Value tend to understand elementary math Students who struggle with Place Value tend to struggle with elementary math

Place Value is demonstratedmany ways in curriculum Place Value is demonstrated many ways in curriculum Place Value From expansion of numbers to explanation of numbers within their different place. Here are some examples of assorted Place Value exercises on MathLine…

Simple Expansion of 17? Place Value – Expansion

Note: Red ring is 10 Place Value – Expansion

How many tens and how many ones in 17? 10 1234567

Simple Expansion of 46? Place Value – Expansion

Note the number of red rings Place Value – Expansion

How many tens and how many ones in 46? 10

Place Value – Expansion How many tens and how many ones in 46? 10

Place Value – Expansion 10 RULE – if we begin a group on one bar, it continues on the next. RULE – if we begin a group on one bar, it continues on the next. 10

Place Value – Expansion 10 RULE – if we begin a group on one bar, it continues on the next. RULE – if we begin a group on one bar, it continues on the next. 10

Place Value – Expansion 10 How many ones in 46? 265431

How many tens in 20 ones? Place Value – Expansion

Note red rings Place Value – Expansion

Two tens in 20 ones Place Value – Expansion 10 How many tens in 20 ones?

Show the relationship between 15 and 51 Place Value – Expansion Students often struggle with understanding the difference in value for similar numbers like 15 and 51

Show the relationship between 15 and 51 Place Value – Expansion

Student can “see” the difference. Place Value – Expansion

1 Groups of ten in 15

Place Value – Expansion 12 3 3 45 Groups of ten in 51

Place Value – Expansion 1 “Ones” in 15 2345

Place Value – Expansion 236 100 200 300 100 200 36 62 Using multiple MathLine’s show relationship between 362

362 Place Value – Expansion How do the “2’s” relate in both numbers? 100 236 362 100 200 300 62 200

Place Value – Expansion 100 62 236 362 100 200 300 62 100 200 The “2” in “236” is two groups of 100. 362

Place Value – Expansion 100 62 236 362 100 200 300 62 200 362 While the “2” in “362” is two “ones” 6262

Place Value – Expansion Show the relationship between 236 and 362 How do the “3’s” relate in both numbers? 236362 236236236236 362

Place Value – Expansion 236236236236362362 The “3” in “236” is three groups of 10. 1 2 3 3

Place Value – Expansion 236362 362 The “3” in “362” is three groups of 100. 100 200 300

Place Value – Expansion Show the relationship between 236 and 362 236 362362362362 How do the “6’s” relate in both numbers?

Place Value – Expansion 236 362 The “6” in “236” is six “ones”

Place Value – Expansion 236 362362362362 The “6” in “362” is six “tens” 1 2 3 3 4 5 6
