As children become more confident in their math skills, give them worksheets one grade level above their current grade. Help them if necessary, but when students become successful in the upper level workbooks; their confidence will really improve. The seed will be planted early and parents can watch as it grows.
In order to develop a student that has good math skills, a parent must play a key role in the learning process. In addition to parents, teachers and other family members are very important to a child's mathematical development.
Sort it out! The sky is the limit when it comes to finding things to sort! Candy, beans, cotton balls, paper clips... you name it! You can even change around how you want it sorted... one time, sort by color, the next time sort by size or shape! My son had a BLAST when I pulled his Matchbox cars to the school table and we sorted them by color! For younger children, you can make it easier by having 'color cards' and have them match the specific objects to the correct card. Older children can just be told to sort out the items by color, shape, etc.
If you are a swing trader or a position trader, it is easier to maintain a trade-by-trade trading journal. However, a day trader or active trader may find it difficult to document each trade, so a general sentiment of how he is maintaining his system and the overall sentiment on the day may be more appropriate. As you learn some of the various risk management techniques, it will become simpler to use a trading journal on a per-trade basis. Until then, let's take our time.
