Place Value

We continue with our work with understanding place value. Students understand so far that double digit numbers are made up of groups of tens and ones. We have used the 100 chart and the 120 chart and studied them for patterns relating to the position of tens and ones.

In the coming weeks the students will be working on adding and subtracting multiples of 10 with two-digit numbers.

Here are some skills we are working hard to master:

Essential Vocabulary
bundle, column, compare, compose a ten, digit,  greater than/more than (>), hundred chart, less, less than/fewer than (<), ones, ones digit, row, tens, tens digit


- Expressions and equations can represent real-life situations.
- Our number system has structures based on groups of 10.
- The sequence of numbers follows a predictable pattern.
-The names of numbers within 120. {Several students have trouble writing numbers between 100 and 120, continue practicing this at home}
- A ten is a bundle of ten ones (unitizing).
- Multiples of ten (10, 20, 30..,) represent groups of tens and 0 ones.
- A digit in the tens place represents bundles of ten and a digit in the ones place represents loose ones or singles.
-The digit in the tens place is more important for determining the value of a two-digit number than the ones place.
- How to make sense of quantity and be able to compare numbers.
- The meaning of the symbols >, =, <.
- The equation must have the same value on both sides of the equal sign.

Upcoming Assessments :
- Math fact assessment: basic recall of addition and subtraction within 20 **I'm noticing not as much fluency with facts as I would like to see at this point in the year. Please help with this at home. **Flashcards can be found pretty inexpensively. Also feel free to use online flashcards: http://www.varsitytutors.com/aplusmath/flashcards
- Story problem formative assessment: our next formative will include a higher order thinking question with an emphasis on justifying answers/explaining their thinking. This is a large focus for the remainder of first grade and an important skill going into second grade.
- Parkway math benchmark assessment

Moving forward our math concepts will continue to become more complex as we look towards being prepared for second grade. Please take a peek at math work coming home to see exactly what we are working on and for feedback on your child's understanding of topics and concepts.
