Your kid is not as smart/stupid as you think they are.
You are not as smart as you think you are.
Set your expectations for the day low & then lower them again. Teaching your own children is a VERY STRESSFUL EXPERIENCE & it may break you.
You will need somewhere to work. If you have the space, a dedicated table in a central area is great. If not, be prepared to pack everything away for meal times.
The floor is not great. Kids will complain, your back will break & your knees will kill you.
Scissors
Glue
A whiteboard & markers (doesn't have to be huge A4 size is fine)
Scrap paper (tonnes of paper actually)
Stickers for rewards/bribes.
Stapler, tape, holepunch, sedatives.
Colouring pencils etc
If at any time you are stressed & upset or the kids are upset stop what you are doing straight away. It is obviously not working. Take a brain break. Let the kids play/read/snuggle with their pet.
Let's get specific.
Early Childhood Kids - kindy/preschool to Year 1
(don't @ me teachers this is general information only)
Luckily for kids most learning at this age is play based.
Extra printer ink
Especially colour ink.
Make sure your IT is working in advance because not being able to print something will end in tears & a broken computer.
School work is getting more serious now and so it should be, they're consolidating (see proper teacher words) everything they've learned before & building on that.
