math-drills.com - K-9th grade worksheets

Good resource site for decimal, fraction, other arithmatic, algebra and geometry worksheets. Has a variety of pages so kids can get enough practice at each step.

ReadWriteThink.org

Excellent quality site with classroom and parent resources. Some topics are covered only generally, but many have concrete and immediately useful content. The first one I checked out was the 'Hink Pink' - a word game in which one player gives a two word clue for a two word rhyme, like 'fake cash' for 'funny money'. See http://readwritethink.org

Scratch with Friends

My 6 year old came up with this one: invite your friends to each add a character to a game, and see what happens.

1/3

Summary: 

Here is another opportunity for discovery: one-third. For kids who have learned how to divide and get decimals (or show a child briefly who has learned long division and knows what decimals are). Ask simply, what is one-third in decimal?

The discovery that 1/3 = .33333333... the repeating decimal, is surprising enough on its own for a child who has never seen an infinite series before. What usually will tweak their curiousity, though, is to continue - ok, what is 2/3? Then wait a moment, and see if they think of 3/3 by themselves. The idea that 3/3 = .999999999... may get the child saying, wait a minute - 3/3 = 1!

Zeroth power

in
Summary: 

For kids who have been introduced to exponents but haven't been taught specifically about what it means to take 'N to the zero power', this is an opportunity for a small 'Aha!' moment.

If a child already knows what is ten to the 2 (102 = 10 * 10 = 100) and 101 = 10, ask them what is 100.

Let them think a bit. Many kids will answer 'zero'. Ask, well, then what is zero times 10? If its not 101, then that can't be right.

Explain that 100 must be the thing that you multiply by 10 to get 101. This should be enough of a clue that they realize that 10 to the zero is 1.

"Aha!"

Every kid can potentially make the same exciting discoveries that Archimedes, Galileo, Pythagorus and other greats did - with a bit of guidance and preparation. Every kid won't make every discovery, but look for opportunities to prepare the groundwork, guide and let loose so they can have the fun of figuring out something fundamental for themselves.

How many days in your week? (or, modulo arithmetic..)

in
Summary: 

Here is a fun way to introduce kids to the concept of modulus (without ever saying the word): ask, why does a week have 7 days? Suppose you could change it - how many days would you put in the week? Then ask some questions about 'in X days, what day would it be?'

It helps to ask the child to consider the days as being named by number at first, to look at the patterns, starting with Zero-day and continuing as One-day, Two-day (which conveniently becomes Tuesday if Sunday is Zero-day), etc.

Start with simple questions like "So if your week has 5 days, and today is Three-day, what day will it be in 6 days?"

Make sure to ask several with the modulus "If your week has 4 days, and today is Zero-day, what day will it be in 4 days? 8 days? 16 days?"

NOTE: the '_' symbol on problems #3 and #4 is meant to be a X (multiplication sign). Make sure to fix this on the printout before your child thinks there is a new arithmetic symbol she never learned!
