Fine Arts
circle shapes.
Visual Arts
2. Make sure each student has a plus and equal sign of his
own. You must take the time to discuss the signs and how
they are to be used. Model the use of the signs with some precut PLAY-DOH shapes. At this time,
demonstrate how PLAY-DOH number sentences should be constructed and used to find the sum of the
addition fact.
3. Using the precut shapes, encourage students to make the PLAY-DOH number sentence 2 + 1 = ?
4. Students then count both sides of the equation to find the answer. Continue to give number sentences for
the students to build at their desks and solve. You should keep the plus one on the right side of the
equation. Later as an extension the numbers could be mixed.
