I'm looking for lesson ideas that are appropriate for elementary students

Mannimar

So I work in an elementary after school program, and we run a few curriculum with them: math, science, English, and special activities like art, drama, and other fun things. Now, my location has the pleasure of being the smallest running program, so small that I have to work with all age groups at once. On top of having an incompetent supervisor who mostly buys art supplies and doesn't advocate on our behalf. This winds up in me running out of supplies for our provided curriculum. I've started putting together an alternative curriculum for these situations. Science activities out of everyday items, math games with a deck of cards, ect. 

This is mainly directed at you teacher types, but if you have any lessons that you would be willing to share, websites, Pinterest posts, anything at all, I would greatly appreciate it. I'm okay with making small investments, so spending a little money won't be too problematic.

age appropriate worksheets, word scrambles, crosswords, word searches, etc.  You can make your own online. Somewhere. I'd link you if I weren't being lazy.

dictionary races with their spelling words, or around the world, or spelling bees. 

Read-aloud story time, if they had a story in ELA that they particularly enjoyed that week, they can share with the rest of their group or you can pass the book and everyone gets a paragraph.

story Mash - form a sitting circle. figure out who goes first. Tell a story where the second person has to pick up from the first when they stop (better for older kids because of paying attention to detail issues).

individually wrapped life savers are the safest treats i've found for today's hyper-allergic society. If they start getting whiny over what colour/flavour, they don't get the treat (mean, but saves a tonne of stress and being left with nothing but green). They are allowed to trade, but no wrappers may be left or they get put on 'clean up the whole room' work next session.

hmn. 

have a Stomp day or three, if you want to do music - watch the video (or two shorter segments), then go through backpacks and lunch boxes and purses/bags to find new 'instruments'. Go through some basic rhythms (write them out on chart paper/on a board if you are able), then have them switch up parts until everyone's had a turn on all the rhythms.

history stuff....ask them what they've learned about and write a short skit. Make costumes with all those art supplies. 

math...break out the mad minutes. There's also a game called 24 where there's four numbers on a card and the kids have to figure out how 24 is achieved...this times that plus that divided by this other one is 24, etc. Can also do long division drills on the board, ala around the world (again, if you have a board OR individual dry erase boards)

statistics/math/social studies - take polls. Who's played this video game, who does karate after school. Draw graphs. The kids will get to know each other better and become a tight knit group. 

You know....all this stuff teachers don't have time to do anymore because we have to teach to these stupid tests and then get yelled at because scores aren't high enough so we have to revise revise revise plans in all our time.

foreign language - draw an alien and label its body parts in whichever foreign language. colour it and make it pretty.

Stay the hell away from glitter.. it's the herpes of the art world. It gets everywhere. 

EVERYWHERE.

Depending on how you feel about mess, Elephant's Toothpaste is a good chemistry demonstration.  The standard version uses 30% hydrogen peroxide, which you probably don't want around children - but there's one here that uses a 3% solution:

In fact, that website has a load of child-friendly activities.  Not sure how the cost of them is, but a quick glance looks like they're designed to be cheap:

Also, some posts here and here about using demonstrations to teach science, rather than just show it.

And some maths puzzles:

Have the kids take turns picking a body part and a number. They then have to draw monsters that have that many parts, I.e, three eyes, twelve fingers, a bajillion hairs.

Zeon

Teach them lambda calculus.

I always liked the simple things, construction paper and scissors to create something like Oragami or a fun thing I did once with some kindergartners was have them make paper air planes and teach them about science that way. Oh  a rube goldberg machine! Those are so fun to do and they are science based as well!

If you do the paper airplanes make sure you make them with FLAT NOSES!!! Those brats will throw them at each other! Make it a contest too!!! Who ever makes the best airplane that goes the farthest although I never liked making it a contest but if it's something fun they will like go for it.

But srsly, the Rube Goldberg is boss kids love it.

Alright I was tired last night so I didn't get to finish. Simple things to make Rube Goldbergs are!

Dominos
Kinex - lego things
Legos
Pretty much anything!

The fun is having them make their own most will just stack dominoes and push them over. FYI.
