We've just recently started to use some of the charts from Doorposts and let me just say what a great tool this is for parenting and character building in our kids! Thanks to the FIAR board ladies for as always recommending the best products available for moms and homeschoolers.
The chart we are primarily using is the IF-THEN CHART. This chart has 3 columns. The first column has a funny cartoon that describes a "IF" situation common to a child (arguing, whining, lying, hitting, etc.). The second column has a BIBLE VERSE that speaks about that sin issue and the third column is "THEN" column where you will write a consequence for that behavior. On the back of the chart there are suggested consequences.
The other chart we bought is the Blessing Chart, which has godly behavior such as sharing, gentleness, kindness, etc., a verse that speaks about the reward that comes from such behavior and a space to write a simple reward. I love the fact that they suggest you use a simple reward that reinforces the Bible verse. Very creative and a great way for kids to remember what the word of God says. Here's an example...
Godly Attitude: Obedience
Verse: "If you walk in my statutes and keep my commandments...then I will walk among you"
Reward: Special walk alone with parent
Godly attitude: honoring parents
Verse: "honor your father and mother that your days may be long..."
Reward: no nap, or later bedtime or play outside longer
If you are looking for something to help you be more consistent on disciplining your kids, you need to take a look at these charts.
