Style 1 - Linear
For the serial number - Insert a square text box and write down the numbers in big and bold
For the text - Insert a rectangular text box
Style 2 - Photograph
Choose an image which depicts 'an agenda' or relates to the topic of your presentation. Insert a text box in a colour of your choice. Prefer a colour which is in stark contrast with the background image.
Blur the image - Click on the image. Go to format (you can see it up there in MS PowerPoint 2013). Choose BLUR under Artistic Effect. The image will become slightly hazy. This will bring the text in focus.
Transparent text box - Right click on the text box and choose Format Shape. Under FILL, choose transparency and choose 10%. You can play around with this number and see how the slide looks.
Style 3 - Icons
Download these icons from sites like iconfinder.com or similar other sites. Ensure the icons are of the same size and represent the text. Icons look good when you have 3 to 5 items in the agenda. For more items, prefer Styles 1 or 2 above.
