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.
Ten and Some More
Double Ten Frames
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+ 29 + 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.
