3 Welcome to the September, October Edition of Let s Make Math Fun. This issue has developed into a Dots and Dice issue. It certainly wasn t intentional but as it came into being, I found Dots and Dice seemed to feature prominently! In this issue, I welcome Alison Hislop as a guest writer. Alison is an Australian teacher. I came across her blog several months ago and was impressed with her great ideas and her passion for making math fun for kids. So impressed in fact, that I really wanted to share some of her great ideas here with you! Halloween also features in this edition but don t worry if you don t celebrate Halloween as these games, activities and ideas are either adaptable or provided in a non Halloween version also. Hope you and the kids enjoy this issue s games and activities! Teresa 3

4 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 - Measuring with a Scarf! A fabulous winter activity as it starts to get cold... burrr! From my "Great Ideas" page at 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! 4

5 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! She has loads more great ideas on her blog. Teaching Maths With Meaning She also has lots of great math products at her TPT store

6 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) 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, and Write Chart, and Write Number Chart and 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 and Write Record Sheet is used for all of the above. Hope the kids enjoy having the dice tell them what to do! 6

15 Dots Game for Math Facts You are probably familiar with the pencil and paper games Dots! It is a game for 2 players. If you aren t, here is how it is played. Draw a large grid of dots e.g. 10 dots by 10 dots. Each player takes turns to join two dots with a line (dots must be adjoining, only vertical and horizontal lines allowed). When a player puts in the 4th line to make a small square they put their initial in the square and have another turn. As the grid fills up you may be able to make many squares in one turn. The winner is the person with the most squares. Dots Multiplication Now that you know how to play, you can easily adapt this to play Dots Multiplication. It is played in the same way with each player trying to make as many squares as possible. In this game though, each dot contains a number. A player can t join 2 dots until they have multiplied the 2 numbers together. So if a player wants to join 4 and 9, they first have to say 4x9=36. While the game is being played each player could check the others multiplication using a calculator. Dots Addition or Subtraction The game could also be used as an addition or subtraction game with players adding the numbers in the dots or subtracting the smaller number from the larger one. On the following pages, you ll find three printable game sheets for Dots for Multiplication, Dots for Addition and Dots for Subtraction. There is a basic Dots game at the top of each sheet so that students can first practise the basic game and then move onto the other version

21 Halloween Math Game I included this simple game in a magazine a few years ago and it proved to be quite popular so I thought I would add it here again as Halloween is getting closer! This is a simple math Halloween activity that requires very little equipment. It is called Four Dice Skeleton. The class can be divided into teams for this game or it can be played by groups of three or four children. To play this game, you will need four dice. Start by writing the alphabet across the board or on a piece of paper. Under each letter write a number value starting with 1 for a, then 2 for b, etc. Each player or team also draws eight dashes ready for the word skeleton to be written on the dashes. The object of the game is to be the first player or team to complete the word skeleton. Players do this by throwing the four dice and adding the value of the numbers. They then look at the alphabet chart to see which letter corresponds to this number. If it is one of the letters in the word skeleton, they can write the letter in their word. For example, if they throw a five with 1, 1, 1, 2 they can write in the e s into the word. This game can take a while to play so it can be shortened by having only one word to be filled in instead of having a word for each player or team. The winner in this version is the person who completes the word by adding the last letter. The game can also be played with other Halloween words such as monster, frighten or pumpkin, but don t include words with the letters a, b, c, d, y or z as with four dice the children won t be able to throw the corresponding number value. Such words can be used though if these letters are written in before the game starts. Non Halloween Version If you don t celebrate Halloween with your students or your children, you can easily adapt this game by changing the word that is being made. Choose the name of an animal, sport, cartoon character or any word appropriate to current studies. Just make sure that the word doesn t contain any of the letters a, b, c, d, y or z
