**ELEMENTS** :

**ADDITION & SUBTRACTION 21 – **COUNTING FORWARDS & BACKWARDS IS ADDING & SUBTRACTING 1 EACH TIME**
ADDITION & SUBTRACTION 22 – **ADD & SUBTRACT COUNTING BY ONES USING COUNTERS

**ADDITION & SUBTRACTION 23 –**ADDING & SUBTRACTING ZERO DOES NOT CHANGE THE VALUE

**ADDITION & SUBTRACTION 24 –**ADDING & SUBTRACTING ON A NUMBER LINE

**ADDITION & SUBTRACTION 29 –**FINDING DIFFERENCE BY COUNTING ON AND COUNTING BACK

These Addition & Subtraction Elements are explicitly taught and investigated. When a student has demonstrated and explained their understanding of an Element, that student moves onto the next Element.

The ELEMENTS in this group are intrinsically related because counting has an empirical and logical basis to Addition & Subtraction concepts because both involve additive thinking and algebraic thinking.

*NB: The Teaching Resources have been linked below as a complete document containing all Elements (button 1) and as each individual Elements (buttons 2 3 4 5 6). Button 7 is the Problem Solving PowerPoint.*

*The remaining buttons are the Videos.*
