Zoom for 1 host and 400 attendees for 5 days 2hrs daily

[SRam]

HI, I'm a college student and going to teach kids during my break for free. What will be a suitable zoom meeting account that 400kids attend and I'm the only host, it will be a 5 day 2hrs daily free class for kids. Appreciate if you help me to choose the right plan and also is any promo codes. Thanks

Please guide me on which plan to take

Welcome to the Zoom Community, @SRam.

You need a Pro account to have meetings over 40 minutes; you need the Large Meeting Add-On to have over 100 attendees. As an alternative, you might consider a Webinar license, which starts at a 500 attendee limit. 

If you are only going to do this over the holidays, be sure to indicate you only want the Monthly Non-Recurring license.
