Week 9, 2020

Summer weather is here along with the end of our 2020 school year.

Did you know you can enjoy math outside?

Keep counting, playing, and helping your family.

I look forward to seeing you in September!

Email me and we can play this week’s game together.

Just for Laughs: What is a math teacher's favorite sum?

Summer Sums

Gather sticks to make

several bundles of 10 for the TENS place

and several single sticks for the ONES place.

Use your sticks to calculate the sums for these expressions:

17 + 83 48 + 52 75 +25 36 + 64

Make up your own expressions to solve!

Something to Discuss

Bees love dandelions!

How many whole flowers do you see?

How many flowers have a bee on them?

If each bee visits 35 flowers, how many flowers will these bees visit? How did you calculate that?

There were 9 bees before this photo was taken. How many flew away?

Go outside and count as many dandelions as you can. How did you count them? Did you count more than 100? Do not disturb the bees!

Two of my digits are odd but my ONES digit is even.

The sum of my digits is 10.

I am between 100 and 150 but I am NOT 136!

Family game

Watch game here: Place Value Knockout

Just for Laughs Answer: SUMMER!

Place Value Knockout

Need: 2 players, 4 dice (or the Ace, 2, 3, 4, 5, and 6 of each of the four suits out of a deck of cards), paper and pen for recording, place value game board as shown, Lego pieces-a color for each player

One player rolls 4 dice (or draws 4 cards) to create a 4-digit number, say the number but don’t say “and”, and record it on the recording sheet.
Place one piece of your color Lego on each of the corresponding place value squares.
Next player rolls, creates a 4-digit number that uses place values that have not been knocked out, says it, records it, and places their Lego pieces.
Alternate who goes first on each round.
Play continues for 5 turns.
Player with the most Lego after 5 turns wins!

You could play this outside! Just draw the place value board with sidewalk chalk and use chalk colors to claim your place value squares!

Week 8, 2020

I hope you are staying positive.

Fresh air and sunshine help even with black flies!

I hope I can play this week’s game with you.

Contact me and we can "meet".

Riddle Answer: Mothematics

A guy thought it would be fun to have a strange pet. So he went to the pet store and bought a talking centipede (100-legged bug), which came in a little white box.

The guy took the box home, found a nice spot for it, and decided he would start off by taking his new pet shopping. He asked the centipede in the box, “Would you like to go to the store with me? We’ll have a great time.”

But there was no answer from his new talking pet.

This bothered him, since the bug was supposed to talk. He waited a minute, then asked again: “How about going to the store with me to shop?”

The guy waited and waited, but again, no answer from the centipede.

Finally the guy put his face right up against the centipede’s house and shouted, “HEY IN THERE!!! Do you want to go out to the store with me?”

A little voice came out of the box: “Chill out, I heard you the first time!! I’m putting on my shoes.”

Something to Discuss

My friend, Janine is growing plants for her garden!

These are tiny cucumber seedlings.

How many plants do you see?

How did you count them?

Count on to find out how many plants you would have if all the pots had 2 plants in each.

Family game

GET OUT OF MY HOUSE!

Need: 2 or more players, deck of cards (Ace to 10), 7 tokens of any kind each, a drawing of a house with 20 squares numbered 1 to 20

Take turns to turn over 2 cards. Add or subtract the 2 cards and put your token on the number that matches your sum or difference.
Next player repeats this and if they can land on a square taken by another player, they shout, “GET OUT OF MY HOUSE!” and replaces the token with one of their own.
One player can have more than one of their own tokens on the same square but they risk having all of these tokens kicked out of the house and replaced by an opponent’s token.
Play continues until a player has placed all 7 of their tokens on the house.

HEAD SCRATCH-ER

SOME THINGS TO DISCUSS

What do you notice? What do you wonder?

Did you find the total amount of money on each side? If not, do it now!

Which side was easier to add? Why? What strategy did you use to add?

How many quarters are in a dollar? How many nickels equal a quarter?

What coins could you use to make 25￠? Do you know what animal is shown on a quarter?

Hints: They live in Newfoundland Labrador and in Canada’s far north. They are related to reindeer! It is not a moose or a deer.

FAMILY GAME: Love the Loonie

Need: dice for each player and coins (real, play, or homemade)

Everyone starts at once. Everyone races to make exchanges to get to a loonie:

Roll the dice and take that many pennies. Once you have 5 pennies, make an exchange for a nickel and so on.

Continue to make exchanges until you reach the “Lovely LOONIE”!

Here is a link: Love the Loonie

JUST FOR LAUGHS answer: They both have four quarters!

Something to Discuss

Baking can use a lot of eggs. Have you been baking? Bakers ARE mathematicians!

Did you know that when you bake and cook you are using your math skills?

Last week I made a double batch of "Everything" cookies. My recipe called for 1 egg. How many eggs did I need when I doubled my recipe?

How many eggs do you see?

How did you count them?

How many eggs were there when all the trays were full?

How many did I use?

If there were the same number of brown eggs in each tray, how many were used from the third tray?

How many brown eggs were there in all 5 trays?

Did you notice something different about these egg trays? What is a full carton of eggs usually called?

Family Game

Answer: DOZENS

CLOSE CALL

Answer: DOZENS Answer: DOZENS Need: 2+ players

Deck of cards with 10's, jacks, kings, jokers removed

(Ace = 1, Queen = 0)

Deal each player 6 cards
Each player selects 4 of their cards to create two 2-digit numbers so when the two numbers are added together they are as close to 100 as possible without going over.
The player with the sum* closest to 100 wins the round and records 1 point.
After 5 rounds the player with the most points wins OR continue playing rounds until someone reaches 5 points.

*sum means the answer when you add

For younger players, deal 4 cards to each and select 2 cards to get as close to ten as possible, without going over.

To practice subtraction instead, change the rules to subtract 2 numbers to get as close to zero as possible.

Week 4, 2020

If you want help with ANY math please call or email me!

Reflecting on Week 3

B: Last week I felt brave to sing for you.

G: I found out that getting better at anything takes a lot of time!

L: I am learning how to make a website. I will never be a website designer but that kind of perfection is not my goal.

N: New things, like rewriting songs, or teaching from home are chances for me to learn.

I hope your brain is growing!

Maria went to the store to buy a loaf of bread.

She had 2 quarters, 4 dimes, 3 nickels, and 2 pennies.

The total cost of the bread was 82￠.

She promised to make sure she had exactly 1 coin remaining after the purchase.

Which coin did she have left after buying the loaf of bread?

Another reminder...here are our Canadian coins. Try to practice the names and match them to their values

Riddle: What happens once in a lifetime, twice in a moment,

but never in one hundred years?

Hi CES Students. I hope you are finding lots to keep you active and happy. Try to remember to thank the people who are taking care of you. Keep learning and playing because playing IS learning. Try to be brave and try new things. Here is one scary (for me) new thing I tried. I hope you like it!

If you want help with ANY math, please contact me.

DICE DIFFERENCE*

needed: 2 dice, paper, pencil, 2+players

*difference means the answer when you subtract or compare

roll 2 dice, take turns
find the difference, subtracting the lower number from the greater number on the dice
if your difference is 0, 1, or 2 you record a point-use tally marks!
if your difference is 3, 4, or 5 ...no point
play + or - 25 rounds and celebrate the winner
ask if the game is fair, why or why not? do you agree, why or why not?
change the rules: maybe Player 1 gets a point for differences of 0, 1, 2 and Player 2 earns a point for differences of 3, 4, 5. Is the game fair now?

Check out Mr. McQueen's website for his video that shows how to play our favorite Shut the Box game at home!

Riddle Answer: The letter “M”

I had to share the spring beauty of these forsythia branches from my friend’s garden!

How would you count these flowers? How many flowers do you see?
Start at that number and count to 100.
How are two of these stalks the same? Which one does not belong?
If there were 2 more stalks like the first stalk, how many flowers would there be?
How many more stalks would you need to have at least 100 flowers?
Spring is here! Flowers are beginning to bloom. Look around your yard and see if you can find any new green leaves, grass or flowers.

If you are making a grocery list but do not have a piggy bank, maybe you could draw, label, and cut out some paper coins (as many as you like). Then you have some pretend money to start planning your shopping list!

Here are some pictures to help. Use the amounts with the cent symbols (5￠not the dollars $0.05) as you have not learned about adding with decimals yet.

Remember to practice naming coins to help you connect their values with their names.
