Mrs. Martin's Math Site 2019
If you view this website on a translated page you will not see the grade level pages at the very top of the site, be able to listen to the words I recorded in English, or watch videos. All of those are available on the English language version of each page.
Week Six, May 4- May 8 Mrs. Martin is a Birder! Are You?
One of my most favorite hobbies is birdwatching. Spring is when the migrating birds return to Maine. April break gave me the opportunity to spend nearly everyday outside watching, listening to, and identifying birds in my backyard and neighborhood. Now that we are back in school I take a walk each afternoon with my binoculars. Look at what I spotted so far this season. A good birder makes a list of all the birds they identified, so I figured why not put that list here for you all to see (and count)! (Please note, these photos are not mine. They are just Google images I found. Keep scrolling down and you will see actual videos of birds I took in my yard or neighborhood.)
Great Blue Heron
Black and White Warbler
Black Throated Blue Warbler
Ruby Throated Humming Bird
Yellow Throated Warbler
Black-Crowned Night Heron
Great Crested Fly Catcher
Blue Headed Vireo
Mrs. Martin's Bird Videos

A Downy Woodpecker, an American Robin, and A Hairy Woodpecker in my yard.
NOT a bird video, American Toad calls, this was new to me and AWESOME!! (I didn't see any toads, just surrounded by their calls in Hinkley Park.)
An American Robin hopping around my yard.
Cardinal Song on my street.
Hard to see, but this is a video of an American Redstart and a Black Throated Blue Warbler flying around in Hinkley Park.
A Black Duck dabbling for food in Hinkley Park.
Two Black-Crowned Night Herons perched (and flying) in Hinkley Park.
Week Four, April 13-16 Mrs. Martin's Rocks
I don't just collect sea glass. I also collect rocks. I have collected rocks my whole life. I have them in my house and outside too. I had to move all of these rocks from this rock garden. So I wondered, how many rocks do I have in this collection? Let's find out!
I put all the rocks in the wheelbarrow. Then I dumped the pile out in another spot.
Make an estimate. How many rocks do you think there are?
I started my count using ten frames. How many so far?
That's what's still left in the pile. Want to revise your estimate?
Ready to count the whole collection? Each ten frame or circle has ten rocks.
Then there is one rock left over. How many rocks in all?
(There are 18 ten frames and 20 circles of 10.)
These were my son's estimates and his revisions as we made the groups of ten. His final estimate was 366. How close was he to the actual number of rocks?
Week Two, March 30-April 3
Mrs. Martin's Sea Glass Collection
Hi Everyone! I hope you enjoyed my first post about my backyard wildlife. Update: since posting we had another deer and fox sighting and of course, lots of raccoons! This next math story will be about one of my favorite hobbies, collecting sea glass. You can watch this short video about sea glass to learn more about it. Click here and then click again on the next page. The Secret Behind Sea Glass. Below the video are some photos of my sea glass collection.
You can only see the video on the English language version of my website. The video is the underlined link above. The Secret Behind Sea Glass.
Getting ready to sort our treasures two summers ago.
What an assortment!
Part of my collection in my kitchen.
More of my collection.
Now for some math!
At the top of this website you can click on your own grade level or check out other grade levels, too. There will be videos to watch, photos to look at and problems to solve. Then there is a Google Form with the math problems for you to do and send to me.
Week One, March 23-27 Mrs. Martin's Backyard Wildlife
Watch this first then go to your grade level page.
This is my backyard wildlife camera. Every time an animal walks through my yard, past the camera, it takes a photo. Here are the photos of the different animals photographed.
My children and I collected the data, the number of times these animals were photographed from February 20th to March 20th, and we created a bar graph. Check out our data and answer the questions!
