Teaching Table
Set out your lesson
Use pairs to identify odd/even and split an even set into equal groups.
Can discuss the supplied example in an accessible mode; adapt directions without supplying the target answer.
Check the learner can follow the model with support before moving on. Source prerequisite ordering is not learner mastery; return to prerequisite work when needed.
Draw dots or use large counters; keep final quantities out of sight until T. Open S first, G together, then T alone; put S and G away before T. Keys stay adult-only. No purchase or printing is required; an unavailable physical observation remains pending, not passed.
Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.
What this lesson covers and its limits
These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.
- partial: Determine whether a group of objects (up to 20) has an odd or even number of members
Two independent quantities up to twenty; a universal parity rule is not assumed.
- partial: Pair objects and determine whether there is one left over (odd) or not (even)
Two independent quantities up to twenty; a universal parity rule is not assumed.
- partial: Count a group by 2s to determine if the total is even
Two independent quantities up to twenty; a universal parity rule is not assumed.
- partial: Write an equation to express an even number as a sum of two equal addends (e.g. 8 = 4 + 4)
Two independent quantities up to twenty; a universal parity rule is not assumed.
- partial: If {{name}} has a group of 14 objects, can they tell you whether that number is odd or even — for example by pairing them up to see if any are left over?
Two independent quantities up to twenty; a universal parity rule is not assumed.
