I made this simple worksheet to test Lore’s ability to figure out missing letters in the alphabet. There are only 15 apples on the printable, but instead of printing two, I just did little sections of the alphabet wat a time. She flew right through it! I also tried her on numbers and she had fun practicing writing her numbers and coming up with the missing numbers.
I laminated ours so we could use it more than once, which is what I recommend doing! After, simply use a dry-erase marker and fill in the letters/numbers, skipping some and leaving them empty. Then have you child go through and fill in the empty spots. Easy peasy!
