A whiteboard and marker and some paper was the way I went a while ago along with google worksheets and a printer. Or you can buy workbooks from Walmart, Amazon or Target
You can use things around your house for counting such as cups and cans and what not like that. You can also do color shorting with straws or painted pasta noodles.
The whole idea of homeschooling is being creative and helping your kids learn. One on one time is perfect if you can because kids often learn better with that.
You can cut straws and use a ruler to measure them or you can use the ruler to measure anything.
Planting plants, watering them and transplanting them also are great hands on learning. Gardening is also great. (If you need seeds check out Baker Creek / Rare seeds! Every seed I got from them grew and bloomed. I highly recommend them!)
Kids can pretty much do anything and learn from it. It is not hard to homeschool kids and trust me, if you do the unschooling route it can be a little difficult because it is but you can teach them the way you want and the way they will understand.
If your kid goes to work with their dad and reads the ruler while he putting drywall that counts because they have to do math and reading trying to figure out what the size of the drywall is.
Anything that allows them to count, measure and read can be deemed as school work which is great because they also learn hands on experience and trade work at the same time.
You can also go to thrift stores for books if needed. Temu and Ali express also have cheap homeschooling supplies to help you teach better in which I love.
You can also use minecraft maps for educational in the market place or check out minecraft education.
You can use these apps and websites for teaching and learning. My kids love them.
