Ready for some beachy addition practice? One of these rows of sea shells has five more than the other; learners examine sets to determine which one has five more, checking it off. Consider also asking them to write down the specific number of each set to encourage number value concepts. Next, they practice beginning addition skills by counting sets of pails, adding five more, and calculating the total. There are two of these, and the sums are both single-digit. Again, having them write numerals beneath each set would be a helpful extension.
