spell ie and ei words, dice game: 'Follow the rule/break the rule', i before e except after c

I can spell ‘ie’ and ‘ei’ words

Lots of children (and adults) get mixed-up when spelling 'ie' and 'ei' words. Is the rule 'i before e except after c' actually helpful?

This dice game encourages children to explore the rule and decide for themselves.

Here are some words that keep to the rule:
field, shield, brief, chief, belief, believe, unbelievable, relief, relieved, piece, achieve
receive, conceit, deceive, deceit, conceive, misconceive, perceive, perceivable, ceiling, receipt

Here are some that don't:
neighbour, weigh, counterfeit, foreign, kaleidoscope, their, caffeine, leisure, protein, seize, weird
ancient, deficient, glacier, proficient, society, science, sufficient, species

Play the game ‘Follow the rule/break the rule’, classifying words into two groups. After the game, the class could consider if this rule may work best:
“i before e except after c, but only if it rhymes with a bee!”
