Winter Progress Monitoring & Instructional Strategies for 1.NBT.2


Understand place value. 
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."
b. The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
c.  The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).

Progress Monitoring:
Present student with some cubes.  Ask the student how many groups of 10 do you think you can make?  Have student check and see how many 10's they can make and ask how many groups of 10 did you make and how many left overs.
