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.

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.
