Children will use the Make a Ten strategy in this lesson, along with
other strategies. Remind children that if they are adding two numbers
such as 8 + 5, they can regroup the numbers to make adding easier. Tell
children that they can take 2 from the 5 and add the 2 to 8 to make a
ten. Also remind them that they must remember to subtract the 2 from the
5, leaving a 3, so they add 10 and 3 and get 13. Tell children that
they will use this strategy to add two-digit numbers.
Materials: overhead projector, ten-frames and
counters, tens and ones workmat, bundles of 10 craft sticks and single
sticks, large number line, and large hundred chart
Preparation: Prepare a tens and ones workmat and a
ten frame for use on the overhead. Make 9 bundles of craft sticks, 10
per bundle, using rubber bands to hold them together. Or use tens and
ones blocks. Make a large number line and hundred chart for the
classroom.
Prerequisite Skills and Concepts: Children should know the addition facts to 20 and the strategies used in learning them.
