Compare quantities with counting and matching; explain more, fewer and the same number.
Compare sets to 10 by matching/counting and compare written numbers 1–10.
Kindergarten · 5–6 years · 30 challenges
Compare sets to 10 by matching/counting and compare written numbers 1–10.
Read all directions and choices aloud. Compare individual objects, not their size, group length or container. Use the stated counts and demonstrate matching where requested. Sets stay within ten. Written comparisons use ordinary language; formal inequality symbols are not assumed.
Give everyone time to think and discuss before one pupil acts at the board. The class explains and confirms together; hints and explanations stay until you move on.
Use an up-to-date browser on a computer connected to a whiteboard or shared display. Touch, mouse and keyboard; optional audio and reduced motion. No pupil accounts or personal devices.
Choose from 5 challenges up to the full activity. Discussion determines the duration: you set the pace.
Six represents more objects than four. A set of six has objects left after every object in the set of four is matched.
Teacher: make and match sets of four and six counters.
A has four dots and B has six, so the smaller set contains four. Ten would count both sets together instead.
Explain why combining the sets would answer a different question.
Six remains more than four. Spreading a set changes how it looks, while its objects and count stay the same.
Teacher: make the two sets, rearrange A, and justify the comparison again.
