My 7 year old does great with math-except skip counting! She gets all tongue-tied, stumbles and is frustrated. We quit working on it for a couple of months. I'd like to start it up again so I need some advice/games/rhymes, whatever you used to solidify skip counting. By the way, 5's and 10's are fine. It's 2's, 3's, 4's I like her to learn.
Hopscotch is a fun way to memorize numbers. It helps with rhythm and it helps with agility. Jumping rope as you count is helpful. Ems loved sidewalk chalk. When the weather was nice, we took math outdoors to the driveway.
I just had my 7 year old read the list forwards and backwards once every day. We stopped at 20 for 2s, 30 for 3s, etc. Eventually he could do it without the list. We did one number at a time and when he got it, moved to the next. There are all kinds of catchy songs on youtube if you look up skip counting.
One little thing that might help them to "see" it is to have a 100-chart. I print mine off on the computer, then slip it into a page protector so we can write on it with a wet-erase marker (the dry-erase doesn't work as well with the page protectors I have, but might on others). I have them circle every 3rd, 4th, 6th, 12th or whatever, number, then read off the ones they've circled. Then erase and do it again the next day or every other day.
My daughter is just learning skip counting too right now. I have been having her right the numbers down while saying "write 2, skip 3, write 4, skip 5" so far this has been working for her. But in a month it may not work anymore
My 7 year old's Horizon math book does skip counting with a number line. It seems to make sense to my son that way
Have you ever heard this rhyme? "2, 4, 6, 8. Who do we appreciate? zero, zero, yay zero." That's how my 2 boys have learned that all even numbers end in these. It also got them started with skip counting. They love the cheer too.
