This document summarizes a presentation on major work in first grade mathematics. It discusses exploring place value concepts like unitizing tens and composing numbers from tens and ones. Activities are described like using ten frames, flash cards, and double ten frames to represent numbers from 11 to 19. Students will explore place value tasks involving unitizing tens, composing and decomposing numbers, and using strategies like making tens to add within 100. References and resources are provided for further information.

6. 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.”

7. 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”.

16. 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.

17. Ten and Some More

18. Double Ten Frames

19. 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

16 12 14 16 18
17 12 16 15 17
16 18 14 13 19

21. 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

22. Double Ten Frame
9
+ 3
10
+ 2
9 + 3 = 10 + 2

23. 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”

24. 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.
