Patterns with Paper beads - PreKinder activity

What You Need:

• several colors of construction paper
• a pencil or knitting needle
• glue
• scissors
• yarn
• masking tape

What You Do:

1. Cut the paper into strips (5 inches long and ½ inch wide). Roll each strip of paper around a pencil or knitting needle. Once you’ve formed the shape, slide the paper out and put a drop of glue on the end to hold the paper in place. Press firmly until the glue dries. Repeat using at least two colors.
2. Once the beads are dry, they’re ready to use. Cut a piece of yarn into the appropriate length for your child’s necklace or bracelet, wrap a piece of masking tape around one end to make stringing easier, knot the other end, and set them to work!

Teach your child to string a simple sequence of A-B-A-B. Make sure to say the pattern aloud to help her make the connection between what’s on her piece of yarn, and what she hears. You can say, “This is an A-B-A-B pattern” or “This is a red-yellow-red-yellow pattern”.

4th Grade - Addition game with a deck of cards!

It's a race to see who can hit the target first by working math problems faster than their opponent.

What You Need:

• A deck of playing cards

What You Do:

1. Remove the 12 face cards from the deck and set them aside.
2. Shuffle the rest of the deck and deal four cards face down to each player. Turn the next card face up in the center of the table. This is the target number.
3. At the count of three, all players turn their cards over at the same time. Then they add, subtract, multiply, or divide the numbers on their cards (Aces = 1) and try to equal the target number. All four cards must be used!
4. The first player to equal the target number wins a point, and 3 points wins the game.
5. If no one can equal the target number, turn over another card for a new target number, or deal again.

Here's the winning strategy: keep rearranging your cards until you see the right combination. Also, try to group a pair of cards together.

Another variation would be to put in some of the face cards. They could be wild cards and used in your hand as any number. If the four-card game is too easy, deal five cards to each player.

Prime Numbers - Fun activity for 5th Graders!

What You Need:

·         Colour felt-tip pens

·         A hundreds chart

Review: A prime number is a whole number greater than zero that has exactly two different factors, one and itself. For example, the number 3 is a prime number because its only factors are 1 and 3. In contrast, a composite number is a whole number greater than zero that has more than two different factors. The number 6 is a composite number because its factors are 1, 6, 2, and 3.

It’s important to note that the number 1 is neither prime nor composite. It is not prime because it does not have exactly two different factors. And it is not composite because it does not have more than two factors. 1 is a special number.

What You Do:

1.     Cut or fold the hundreds chart in half if you only want to focus on the prime numbers through 50.

2.    Take a moment to review what makes a prime number. Then let the game begin!

3.    To play, tell your child that you will be competing to cross out all the composite (non-prime) numbers, and circle all the prime numbers. Designate one colour marker for the prime numbers, and another to cross out composite numbers.

4.    Each player will take turns crossing out a composite number (1 point), circling a prime number (3 points), or “passing.” The game will get easier as more number are crossed and circled, but the bigger numbers may present more of a challenge to your child. You may need to take your child through the definition of prime numbers a few times as you look at different numbers.

5.    The player with the most points at the end wins!

After you have played the game, check your answers. The prime numbers through 50 revealed from this activity are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, and 47.
