Google Slides Presentation Design Enhancement

I'm looking for a professional with strong design skills to improve the layout and design of my Google Slides presentation. The main task will be resizing text boxes and images to ensure they fit within the frame on multiple slides. Change all text size to 72 point, resize the text box to fit within the white board background frame, and resize images so that they look nice under the text. This is for a kindergarten class so I will be using this to teach kids. There are 424 slides.

I have attached a picture of what the original slides look like, and what they should look like after you edit them. I will send a google slides link where you can edit.
