Venn Diagrams

Ian and Eric used a Venn diagram to sort their toy animals by diet: herbivores (left), omnivores (center), and carnivores (right).

This fall we have been working on classifying things with Venn diagrams, and then using the data to make tally charts and bar graphs.

Classifications:

• Acorn collection was sorted into acorns without caps, acorns with caps, and caps without acorns.

• Toy animals were sorted according to diet: herbivores, omnivores, and carnivores.

• Halloween creatures were sorted according to day/night activity patterns:  nocturnal, cathemeral, and diurnal.  Most Halloween creatures, for example witches and ghosts, were determined to be nocturnal (active at night).  Cats are cathemeral (active at night & day) and most humans are diurnal (active at day).

We are also working on skip counting (by twos, fives, & tens), writing numbers to 100, recognizing place value (ones, tens, hundreds), addition facts to 10 +10, and telling time to the half-hour.
