What I really wanted to cover was the Ice Age and the early mammals that lived then (woolly mammoths, saber-toothed cats, etc), but I couldn't find books specifically covering that at our tiny local library so I had to work with what I had.
First up we had two DK books that partly covered the era we were interested in. They were Eyewitness Visual Dictionaries: The Visual Dictionary of Prehistoric Life and DK Eyewitness Books: Prehistoric Life. These books actually covered EVERYTHING including the era before dinosaurs, the era during dinosaurs, and the rise of large mammals and neanderthals. We just covered the pages that were relevant to our unit.
Then, we had some storybooks that followed around some of the common animals for that time period.
- Ice Age Monsters: Glyptodon by Rupert Oliver
- Ice Age Monsters: Cave Bear by Rupert Oliver
- Ice Age Monsters: Megaceros by Rupert Oliver
- Ice Age Monsters: Saber Tooth Tiger by Rupert Oliver
- Woolly Mammoth by Ron Wilson
Lastly I couldn't seem to find any relevant worksheets (that weren't coloring pages) to go along with this unit. This unit was fun, and we enjoyed it, but I wish we had had more material to go through.
