Rainy days:Brassy Apple: DIY laser maze kids activity using crepe paper! You would be surprised how easily kids get in awe when u create a unique fun game at home for them.plus this saves you all the dollars you would be spending at the arcade.
ANOTHER GAME TO PLAY WITH THE HERD- Ball Toss. Would also make a great "rainy day" activity. You could even find tubs or buckets of varying sizes (like nesting bins) for more of a challenge for the older kids (Think Skee-ball).
