This activity packet is a great resource for your science lesson on animals that come from eggs!
32 animal picture cards for sorting (fits nicely in a pocket chart)
9 category headers (plus 1 blank)
2 different egg patterns for follow-up activity
In addition to sorting the animals by oviparous (animals who lay eggs) and viviparous (animals who give birth to their young), they can also categorize them in a number of other ways (by physical features, home, number of legs, ways that they move, etc).
This sort is the perfect companion for the book "Chickens Aren't the Only Ones" by Ruth Heller, but can also be used on its own.
