verify that your workflow support the transition from open to in progress. if so then you need to ensure you have permissions or that there isn't some rule/condition that prevents

Adding to What Jack said.
When you would have a notification to your task (either in mail or in jira), check the task, there will be a more option, or you will find buttons with a transition name.

your jira admin or your team could have given custom names for transition to status.
