Math Routine

We have a class set of individual whiteboards and a variety of dry-erase markers. The whiteboards are stored in a milk crate in our classroom.

On one side of the board, I've used packing tape to add a number line from 0-10. You could easily add number lines to 20 or higher - depending on what your students are working on and your focus. I added 0-10 because my SK/1s focused on adding and subtracting to 10 using a number line for Term One - now we are beginning to move on to 20 (the Ontario Grade 1 curriculum).

We do 4 skills at a time. Every 4-6 weeks, we change up our routine to learn and review other skills. Our skills have included:

1. Rekenrek

This is great for subitizing, addition, subtraction, and even multiplication (when using more than one rack). We use the iPad app "Number Racks." There are several YouTube videos showing the versatility of rekenreks. I tell students to write the numeral to show how many beads there are - and extra bonus points if you can write a number sentence to show it!

2. Find the Missing Number

Count forward, backward, and skip-count. I learned a nice trick when at a JUMP MATH conference in Ottawa in November 2016: write your number list vertically to help students see the patterns when skip-counting! This involves Patterning and Algebra and Number Sense and Numeration skills. We use the iPad app called Doodle Buddy.

3. Translate, Extend, and/or Identify the Core of a Pattern

We also use Doodle Buddy for this. You can draw shapes, use different colours, or use the stamps (which make sounds!) to create patterns. Students copy the patterns to the whiteboard (a great time to discuss translating patterns using symbols - or naming them with letters or numbers), extend them, and circle the repeating core.

4. Adding and Subtracting 

We also use Doodle Buddy for this. Students are encouraged to use the number line. I drill into their minds: "Where do we start? Look at the symbol - is our answer getting bigger or smaller? How many bumps? Where did we land?".

5. Representing Numbers using Base 10 Blocks

We use the iPad app Number Blocks. We use this app two different ways:

- Teacher writes a numeral and the students draw it. This is great for introducing place value. "How many long tens? How many little ones?" We represent the numeral then count - which also practices skip counting (by 10s) and counting on (by 1s).

- Teacher uses the blocks to show a quantity. Students write the numeral. We use the questions "How many long tens? How many little ones?" to help students understand place value and what it really means.

See how I track my observations in this blog post!
