If you're looking to get the kids helping out around the house - setting the table, cleaning their rooms - and maybe want to encourage a little more sibling cohesion, this is the chart to use! The Melissa & Doug Responsibility Chart has gotten great reviews from parents, and it's on sale for $18.99 (reg. $24.99) at Amazon.ca!
The chart has a wooden magnetic tracking-and-reward system to encourage good behavior and the completion of daily tasks. Set responsibilities and goals for the week on the left and then track your little ones' progress with the reward magnets under each day of the week.
I'll admit we don't have one of these charts (yet), but I know a number of people that do and love them! Amazon offers free shipping for orders over $35.
You can also get this chart from Chapters for $26.95, with orders over $25 qualifying for free shipping.
