This past week we reviewed how sometimes 2 letters team up and make 1 sound. I held up two fingers (like the peace sign) when we saw a 2 letter team (-ck, -ss, -ll) and then put my fingers together to look like 1 giant finger....the kids did this too...anyway, so when I introduced two letters teaming up to make a blended sound we still held up to fingers, but then, when I blended the sounds I crossed my fingers togethers so it looks liked they blended into each other (does this make sense, think about what you did a little kid when you were telling a fib??)
Anyway, it totally made sense to them and they even did it when they were blending the letters..so they would hold up a finger for b and then a finger for r..then they would say /b/ and then /r/ and then cross their fingers and say /br/.
I hope this makes sense...it really worked for my kids.
