Tips for the Teacher:
1. Very rarely in my high school biology classes do we have the time to devote to a holiday activity. I make an exception each year for this fun, but very important activity. I do this activity each year to remind my students of the importance of community service and “giving back” to our community.
The purpose of the activity is very simple: To put together stockings of candy and Ziplock bags of toiletries that can be donated to a local charity.
2. We donate the stockings and the Ziplock bags of toiletries to our local food bank. You might also consider donating the items to a nursing home, an orphanage, a homeless shelter or the Salvation Army.
3. Check before your donate!! You may need to use only candies that are available in a sealed wrapper. For example, a Hershey kiss is not in a sealed wrapper. The candies listed above can all be purchased in sealed wrappings.
4. Materials needed per student:
- Small stocking
- Quart-sized Ziploc bag
- 1 Hershey bar (I buy a bag that has the smaller bars, but not the miniatures)
- 1 Reese’s peanut butter cup (I buy the regular size, individual cup.)
- 1 packet of M & M’s (I buy a bag of the small packets.)
- 2 Peppermint patties
- 2 small candy canes
- 2 round peppermints
- travel size shampoo
- travel size deodorant
- travel size liquid soap
- travel size toothpaste
- travel size lotion
- toothbrush
These travel-sized toiletries can be found at your local Wal-Mart.
5. The keys above are easily editable. You might choose to include different items. If so, you can easily adjust the dichotomous key for your preferences.
6. Just before Thanksgiving, I place a donation box in my room. I explain to my students that I am collecting their spare change for a service project that we will do just before school is let out for the holidays. I talk briefly about being thankful for what we have, and that we have an obligation to help others who are less fortunate than us. I ask them to place their donations in the collection box whenever they have a bit of change in their pockets to spare. I encourage them to give what they can, and that all donations are a personal and private matter. I accept the donations for about 3 weeks prior to the activity. The students are not allowed to ask each other how much they donated, etc. I use this change to purchase the items needed for the activity.
7. This activity can be used before any holiday by simply changing the clip art at the top of the handout.
8. The dichotomous key assumes that the student will have knowledge of each of the items being classified/identified. I made up these keys as just a fun activity and a way to have my students participate in a community service activity. There is nothing scientific about the activity! Feel free to change the key to meet your needs.
9. “Faveo” is the Latin word for Help. Faveo is defined as: be favorable to, aid, support, help.
10. Terms that you might need to review with your students: homogeneous, heterogeneous, bilateral symmetry, radial symmetry, colonial organism, unicellular organism, anterior, posterior, and epidermis.

Math Activities
Great Math Ideas from Alison Hislop
In this magazine we welcome guest author Alison Hislop. Alison is a teacher from Australia. Check out these great math ideas that she has on her blog - http://MathsWithMeaning.blogspot.com
Measuring with a Scarf!
A fabulous winter activity as it starts to get cold.... burrr!
From my "Great Ideas" page at
http://mathswithmeaning.blogspot.com/p/great-ideas.html
One of my favourite activities to do heading into winter is
to get children to bring in a scarf from home. We talk about expansion (when we stretch our scarfs), line them up next to each other from biggest to smallest, join them together to measure huge distances, measure and compare using measuring tapes, work out the area and perimeter, guess and check how many times we can wrap it around a tree etc. etc.. Who knew you could do so much measuring with a scarf?
Asking the Children....
Today we were consolidating our understanding of place value. We were doing an activity where we needed a 4 digit number and then figured out which number was 10 more, 100 more and 1000 more using MAB.
I had planned for children to turn over 4 playing cards (or 3 or 5 as I differentiated the activity for specific needs) but then I thought,
"Why not ask the children how they could come up with a 4 digit number to use?". So I asked.....
This was their response:
- choosing 4 of our favourite numbers
- picking 4 random numbers
- rolling 4 10-sided dice
- turning over 4 playing cards
- using a calculator, closing your eyes, pushing 4 numbers and then seeing what you pushed (this was by far my favourite, such great thinking!)
Children amaze me with their thinking on a daily basis!

Addition Top-It
Do you know the game Addition Top-It? I have a few different versions but recently discovered another one!
With younger children I play in partners. Each child turns over a card (so there are two showing at once), then have a race to add the cards together and say the answer. The first to say the answer wins the card (if it's a draw, each player gets a card).
As children progress with their understanding of addition and subtraction you can play in groups of three. One person is the dealer and two are the players. The dealer gives each player a card. Players don't look at their card and put it on their forehead so the other player can see their card. Then the dealer adds the two cards together and tells the players the answer. The fastest player to work out what card they have on their head wins. (So many great number strategies are used in this game - best thing is all children playing have to do some Maths!).
Recently, I tried playing this game as purely subtraction practice. Children were in their groups of three and instead the dealer would say "When I subtract this card (pointing to one) from this card (pointing to the other) I get an answer of..." and the players had to guess what card they had. It worked great! Children definitely had to think and remember to always subtract from the big number!! I was so glad I altered this game - it worked so well! I was so proud of the kiddos!
I love Alison’s ideas. She is obviously passionate about making math fun for kids! Shehasloadsmoregreatideasonherblog.Teaching Maths With Meaning

Roll the Dice for Place Value Fun
Let’s look at how dice can be used for teaching and reviewing place value.
There are lots and lots of different ways to use dice to help reinforce place value concepts.
Make the Largest Number
A really simple game for 2 or more players is to have players create
numbers by rolling dice. To create a 2 digit number, they roll 2 dice,
to make a 3 digit number they roll 3 dice. Start the game by seeing
who can make the largest number. The numbers for each round can be recorded on the board or on a piece of paper.
If one player rolls 5 and 3, they would make 53. The other player might roll 1 and 6 and they could make 61. Record both and then award one point to the player with the largest number. After a few rounds of ‘Make the largest number’ with the winner being the one who creates the largest number, try a few different variations.
-Make the smallest number
-Make the number closest to ... (this could be 50 if using 2 digits numbers or 200 if using 2 digit numbers.
-Make an odd number (anyone who can do this scores a point)
-Make a multiple of ... (This might be 5 or 2 for an easy game or 7 or 9 for more advanced students. (anyone who can do this scores a point)
Roll and Write
Another way to use dice to help with place value concepts is the have the dice tell the student what action they are to perform on a number.
You will need dice, Roll and Write Chart, Roll and Write Number Chart and Roll and Write Record Sheet. You will find all of these on the following pages.
There are 3 sets of the charts provided! 2 digit numbers – purple set
3 digit numbers – blue set
4 digit numbers – yellow set
The same Roll and Write Record Sheet is used for all of the above. Hope the kids enjoy
having the dice tell them what to do!
