My clock does not have any numbers on its face, just markers for each hour/five-minute interval. I looked at it in a mirror one morning and noted the time it appeared to be showing. An hour and a half later while eating breakfast in the kitchen I noticed the clock on my phone is showing the time the reflected clock appeared to show earlier. Assuming that both clock and phone were showing the accurate time, what time was it when I first viewed my clock in the mirror? Discussing math in the classroom and at home with your family is so important in developing numeracy, language, and spatial sense! "Which One Doesn't Belong?" Is a great resource to find some math discussion topics! Here is a great example: Can you find a reason why each of the following shapes doesn't belong? (Many more at http://wodb.ca/) Create your own WODB at home! You can use shapes, objects, numbers, graphs, photos, patterns, anything! (Mrs. Clark even created a wodb with picture books her class read together).
You will need 6 coloured counters or squares of paper in 2 different colours (3 of each - shown below is 3 yellow and 3 green). CHALLENGE - Can you go from this... To this? Some rules…
Feel free to download and print the lily pad image below so you can practice, or just draw 7 circles in a straight line to be your lily pads! Hare has challenged the tortoise to a revenge race. Tortoise accepts, but tells hare that any revenge race must be across the rickety bridge. That should help tortoise, because it stops the hare from getting into her jumping rhythm. You can see it is pretty rickety… Here is the bridge with five struts that will break if stepped upon – plunging our poor hare to almost certain death in the torrent below. The hare will win the race if she can make three hops of equal length… The tortoise wins if the hare cannot find three safe and equal jumps in a row. Otherwise the hare wins. So who wins on each bridge? Try a few of the different bridges below. Can you create your own bridge that guarantees the hare will not win? Source: mathpickle.com
Trotter the Turkey wants to collect all of the acorns while avoiding the pesky squirrels.
Can Trotter do this without visiting any square twice? Source: brilliant.org In November we worked on a multiples project, following certain constraints. Students had to fill out the white bubbles with ONLY the numbers 1 and 2. Any 3 consecutive numbers COULD NOT add to a multiple of 3. We defined "multiple" as "The numbers you say when you are skip counting". So, a multiple of 3 would be 3, 6, 9, 12, 15, and so on. A multiple of 5 would be 5, 10, 15, 20, 25 and so on. How many ways can you find to solve the Ring of Threes? There is more than one solution! Could you rearrange the given 3s to make an IMPOSSIBLE ring to solve?
