Contents You may want to use these optional lessons to refresh or introduce key prerequisite skills. Begin the year with lessons found in the Start Smart section. These lessons help students get ready for the coming year by reviewing and reinforcing skills and concepts they learned in the previous grade. The Start Smart lessons also prepare students for skills and concepts they will need for success in the upcoming year. 1 Problem-Solving Strategy 2 Join to Add 3 Separate to Subtract 4 Compare Numbers... 3... 5... 7... 9 End-of-Year Assessment At the end of the year, use the End-of-Year Test to assess student comprehension of the skills and concepts presented in Grade 1.

Use. Write a subtraction number sentence for each picture. Then write an addition fact using the same numbers. 1. 2. 4-2 = 2 2 + 2 = 4 Using the Exercises Exercises 1 5 Remind students that when they want to find the total number of objects in a group, it helps to touch each object as they count. If students need additional help, have them use two-color counters to show the groups and pair the counters from each group to see which group has more and which group has fewer. Help students count the objects using one to one correspondence. How many oranges are in the first group? 2 How many grapes are there? 4 Which group has more? grapes 3 ASSESS 3. 4. 8-3 = 5 3 + 5 = 8 6-3 = 3 3 + 3 = 6 Animal Drawing Have students fold a sheet of paper in half. Point out that the fold makes two work spaces on the paper. Have students draw a group of one kind of animal on one side of the paper. Have students draw a different amount on the other side. Ask students to count and write the number of animals that they drew on each side. Ask students to make a train of cubes to represent both groups. Have students compare their groups and draw a circle around the group that has fewer. 6-1 = 5 5 + 1 = 6 100 one hundred Subtraction Concepts E WRITE MATH Write the word more on the board.
