I created these 4-squares to be compatible with Jolly Phonics. The 42 main letter sounds are included, plus the diagraphs and alternate spellings, for a total of 54 pages in individual pdf files. Students can blend the sounds they've learned into words they know. Each page has 4 words to blend. Students write the focus letter, read the word and then draw a picture to show comprehension. I would begin these on the 2nd round of letter sound presentation (about week 8) so that students have a working knowledge of all the consonants, vowels and diagraphs. This would also work well with any phonics program, giving students practice in blending sounds into words. Review the 4-square with students, then put it into a literacy center!
