Adobe is phasing out Flash, so this could be why you're experiencing issues with our interactives. Luckily, there’s a way for you to have these interactives and activities work even though you may be using a version of Flash that’s not compatible with our site. If you’re using Chrome, there will likely be a padlock icon on the address bar; you’ll need to click that to allow Flash to run. If you’re using Firefox, it should ask you to run Flash, so you’ll need to allow it on the page. If you’re using Safari, you’ll have to download Flash, then enable the plug-in in your Preferences. If enabling Flash doesn’t work, we recommend clearing the browser cache, then reloading the page. We hope this works for you!
