20 "magic number" task cards encourage problem solving and concentration! Aligned specifically with Common Core 4th grade standards, most skills coinciding with Numbers & Operations in Base Ten are incorporated.
Cards range in difficulty. A chart is included with the answer to each card and level (low, moderate, high).
These are best utilized with small groups of students, such as stations. They can also be rotated for a fun morning work assignment! Simply provide students with the animal chart answering sheet, and rotate cards until they have recorded all magic numbers.
