### In This Purposeful Practice…

Students will represent decimal hundredths and perform operations with decimal hundredths, including multiplying by a whole number.

### Intentionality…

The purpose of the Day 4 activities is to reinforce key concepts from Days 1, 2 and 3. Students will engage in a string of related problems through a math talk and will have an opportunity to complete independent purposeful practice. Today’s activities should be completed * without the use of a calculator*.

The math talk and purposeful practice serve to develop a deeper understanding of the following * big ideas*:

**Number:**

- Fractions can be represented in a variety of ways;
- Fractions (and their decimal representation) represent values relative to a whole (for example, one whole pack);
- Quantities represented as a decimal are fractions limited to base ten denominators (i.e.: tenths, hundredths, thousandths, etc.);
- One tenth is one-tenth of one whole, one is ten times greater than one-tenth;
- One hundredth is one-tenth of one-tenth, one-tenth is ten times greater than one-hundredth;
- Multiplication can represent “groups of”, or multiple copies of the same quantity;
- Multiplication is an extension of counting, skip counting and repeated addition.
