Doubling

Doubling

We like mathematical story books. Pulled out today “Alison Hubble, the girl who doubled”.

Then I asked Mya to write down all the equasions in the book and see if she can solve each one before she turned the page to the next one.

She made a mistake on 4th one, I asked to check if she can spot the mistake and fix it. She couldn’t correct it, but she knew where it was. I really wanted to step in and “explain” but stopped myself. I took the materials out and asked her to lay all the equasions out instead, so she can feel them.

She went up to 32, wanted to keep going. Managed 64, then got stuck again. We need to work on Place value more. Gave her a little hint, not to ruin the feel of achievement. She was very proud of herself when she managed the last one.

Number line

Neva become very interested in number line, and she asked if she can make her own by herself, but couldn’t write the numbers no matter how hard she tried. We tried tracing numbers first then writing them, writing them in sand tray etc. but she was still unhappy and kept scrunching up her work. Then she remembered that we had stickers and thus she set to work happily again! She was trying to make it past the 10 into the teens but we run out of 1’s.

Making number line

Counting on number line

Counting on number line

After sticking a number on she’d carefully count all of them from the start, then stick another one on.

Then we found some more stickers (they were bigger then previous ones, so I explained that we need to put 12 on the top, because 11 is taking 2 spaces) and so she finished the line.

When she started I had to explain that the numbers go on or under the notch or a mark on the line, as she was putting them in-between the marks. She did the rest by herself.

Few days later after this post I have watched Christina Tondevold’s video and she says the number lines should only be introduced in grade 2 and instead a Number Path should be used and thinking of it now, it makes total sense. In Number Path there’s no line, no marks, no Zero, so child sees what they need to see. Number line creates confusion for small kids (I have seen it on Neva’s face, but didn’t know why before), but these Number lines are everywhere you look!

Workout for little fingers

This year we went to the PYO farm to get a pumpkin, but I was unorganised and we were too late – the ones on the fields were all rotten, but we were already there and kids wanted to PICK SOMETHING!

So, we found a lot of crops that were not being picked and were going to waste and we took a few things home. Our loot included few sunflower heads, some corn ears and some broad beans that were lying about in the field. Girls were particularly excited about these ones once they have discovered that under the dried out brown pods were very brightly coloured pinkish -purple beans.

We brought our treasure home and without delay they started peeling and shelling things. That was a good workout for their fingers!

We are going to throw in some conkers and some acorns and later on I’ll make them an autumn sensory bin. We haven’t had one for a while and girls love them! Hopefully the beans and corn wouldn’t start rotting. It’s quite peculiar thing happening in this neck of the woods – seeds tend to stat growing at the harvest time instead of saving their energy till next year.  I don’t quite understand it. Some of the corn that we picked started sprouting right on the cob, beans were sprouting inside their pods and acorns in our garden are rooting themselves to the ground! I need to look it up, I am pretty sure that’s not how plant’s self-preservation supposed to work…

After a while of shelling beans I matter-of-factly put some cocktail sticks out and engineering began! I started them off with building a square-based pyramid, hoping to go through some of the other 3D shapes, but they had their own plans, and I didn’t mind. (beans were very soft, freshly picked – this wouldn’t work with dried ones)

Writing with magnets

I have been decluttering recently and came across a big tub of mixed magnetic construction sets that are not being played much with nowadays. I watched them playing with it and realised why. While it seemed like a good idea to me to combine all magnetic sets into one box (MagMax, Geomag, Magnetix and other assorted bits of unknown origin) because the parts looked very much the same, it didn’t work because there were subtle differences (just a few mm) in ball, rod and inserts sizes which meant that the figures that girls were trying to build kept falling apart if a part of a different set was used. It was very frustrating for them, so they quit it altogether.

I will be getting read of the lesser quality ones and will keep the better ones of one brand only and will build up the collection overtime instead by combining sets from the same brand.

But, before I have passed unwanted ones to the charity shop – we have done this fun activity:

Not all the letters could be built, letters with angles are the most difficult ones as magnets don’t stay at an angle, they tend to snap back

Pop the letter!

We really like Styrofoam! We save white and black underlays from pizza and trays from fruits, and this is what we do with them:

First, we write on them with chalks (if black) or markers (if white), then we take a cocktail stick or something pointy and we start popping small holes along the lines, or drawing over the lines with the sticks.

It works great for fine motor skill development! They like the popping sounds, and after they are done with drawing – they usually entertain themselves with breaking the trays. Each time it breaks with a loud pop they squeal and giggle and keep going until only small bits are left.

At some point we used those bits as well to make wind chimes / outside tree decorations/ bird scares on a veggie patch together with the cut-up bits of drinking straws that we made when doing straw cutting exercise . They make a soft bell-like sound or maybe a whisper if you listen carefully.

We tried cutting them with scissors for cutting practice – it works too!

Really want to try doing some Styrofoam etching with them next. Need a half decent roller for that and pigment ink. Anyone got some knocking about they don’t need?

Favourite activities. Bath mats and fine motor skills.

For quite a few of our favourite fine-motor skills activities we have been using ordinary bath mats. We started with small ones of different colours and used them for coloured bead sorting. The younger person started doing it with fingers, then progressed to measuring spoon/melon ball spoon, the older one first was using sugar tongs, then progressed to tweezers. Tweesers are not so easy with wooden Pony Beads, and we broke few plastic tweezers, then I started giving my older daughter smaller, plastic beads and this seems to work.

We also used coloured water and pipette to fill the suckers.

After a while I thought a challenge was in order, so I pulled out a big transparent bath mat and filled up some pots with food colouring, laid some pipets out (mine are re-purposed from some baby medicine) and quietly left it in the middle of the patio…

Smaller person wanted to have a go immediately, she was just experimenting with how much droplets can one sucker cup hold, then she tried mixing few different colours of droplets in one cup and so on.

Her sister came in from school and wanted to have a go too. She first was working on making colour patters, then decided to make a picture.

All in all – good concentration and maths (patterns) practice! And creativity of course!

Maths milk tops and “stained glass” geometry

Little person has been practising her quantity and number pairing with our milk-top dots

img_8459

and doing our favourite shape-sticking today when the sun showed up for a little bit. I have cut up some more file folders as the old one’s colours have faded from the sun. I like the stained glass effect. The brighter the colours the better.

We used these wallets. You don’t have to use geometric shapes, just any shapes you like that will inspire your child to make a picture. You will also need a small spray bottle for spraying on the window to stick the shapes on (can use a travel spray bottles from a pound shop) and a cloth for spillages or when water runs down the window.

I have been busy making some teen and tens Montessori boards (made from cardboard).  And I finally finished Sandpaper cursive letters, only mine are made from corrugated holographic card (anything shiny goes, and neither of us likes the feel of sandpaper)
