Session Agenda • Overview of The Major Work of the Grade • Exploring: First Grade Place Value • Updates • Questions & Answers
NC Educators CCSS Progressions Research Major Work of the Grade Smarter Balanced Assessment Consortium NC Department of Public Instruction
Understanding Place Value • 1.NBT.2 Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: • A. 10 can be thought of as a bundle of ten ones—called a “ten.”
Unitize a Ten • In Kindergarten, everything was thought of as individual units: “ones”. • In First Grade, students are asked to unitize those ten individual ones as a whole unit: “one ten”.
Ten and Some More • 1.NBT.2b The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
Terrific Tens. . .Teens • Understand that when adding ten to a single digit number, the sum is a “teen” • Hold the double ten frames so that the full-ten is on the left and the partial ten is on the right to mimic the way we write double-digit numbers
Composing Tens • 1.NBT.4 Add within 100… • First Grade students use concrete materials, models, drawings and place value strategies to add within 100 • Single digit addition-making tens • Concept that 9+3 = 10+2
Double Ten Frame 9 + 3 = 10 + 2 9 + 3 10 + 2
Nine Plus a Number • Teacher led small group activity • Double ten frame with nine filled in • Student rolls a die and places that number of counters on the second ten frame • Slides one counter to “make ten”
Time to Explore! • Find a partner. • Explore the four Place Value tasks. • Record your “Things I Want to Remember” • If you have any questions, please feel free to ask Andi or Amy.
Tying it Together • What are your take-aways? • What’s Next?
