Ms. Kress’ 2nd grade are using base-10 blocks to represent 3-digit numbers using manipulatives of hundreds-flats, tens-rods, and ones-cubes to build it or by drawing it. They can write numbers in standard form, short form, and expanded form. They are building their math vocabulary, as well.

They practiced the skills with Ms. Kress on the overhead projector as a group, and worked in pairs to get more practice.
