Sentences for correction

Hi Amanda-  I made a few sentences.  Could you please correct them?  I wrote in parentheses what I was trying to say.

1.  Shàng ge zhōumò wǒ gēn zuì hǎo de péngyou dǎ le wǎngqiú.

(Last weekend my friend and I played tennis)

2.  Wǒ kàn de shíhou nǐ, wǒ xiào.

(When I see you, I smile)

3.  Xiàcì wǒ yào yòu yī zhāng xīn de zhàopiàn.

(Next time I will have a new picture)

Thanks!
