Let's solve twenty-four plus six using a hundreds chart. Start by circling the larger addend, twenty-four, on the chart. Then, count up the second addend, six, to find the solution. Did you also get thirty? Let's practice another problem! How can you solve thirty-three plus four using a hundreds chart? Start by circling the larger addend, or number on the chart. Then, count up the second addend or number to find the solution. Did you also get thirty-seven? Let's tackle the final problem! How can you solve forty-five plus seven using a hundreds chart?
