When it comes to matters of estimation, we have all used "the Jar." While this is a valuable visual, we all know that capacity is only one facet of estimation. The cards in this packet will take you beyond the estimation jar to include length, time, and weight, along with capacity.
These 32 colorful estimation task cards are a perfect way to incorporate estimation into your weekly math routine. Simply put one new card on display each week, and set out the printable response cards, then let your students estimate!
