It's not a good idea to have pups jumping, certainly not in a repetitive fashion, before their growth plates have closed at 12 months or so, neither should they be weaving. There are lots of things you could teach though....a good really solid wait and release (for start lines), build play drive and tugging, racing to a food target or toy on the ground (forward focus), running out and round a cone/waste paper bin/chair (learning to work away from you), lots of confidence building and body awareness stuff (introducing to planks/boards on the floor or on little bricks, things that wobble, going through hoops held at floor level, climbing in boxes and bowls etc), teaching tricks like walking backwards, targeting with rear feet, spin left and right, etc. We made some little videos as we were training Dazzle and Whirli, this is the first one (they were about 4.5 months here), might give you some ideas.

The "jump" grid you see in later vids was literally just 4 or 5 passes through, once a week or less, over guttering pipe so no real jumping. As you can see, it's all a huge game, they just adore it!
As for weaving, leave it until Bingley is at least a year old....even using two just for entries will stuff things up if you're planning to teach 2x2s later, staying too long at the first gate results in a dog that just charges poles. Susan Garrett says wait till at least 14 months, which is what I did with Dazzle, and she learned to weave so quickly and so confidently, great entries etc.
