Skill 4A
Two Digit Plus One Digit: Horizontal
Adding a two-digit number with a one-digit number horizontally is a very important skill in being able to properly add 3 numbers vertically.  For example, if your student was adding 25 + 27 + 33 vertically, he/she would first add 5+7, then take that answer (which is 12) and add 3 on top of that.  The problems below practice this exact process.  If your student is doing this correctly, he/she should be using a "count-on"  method (i.e. flying fist) by saying the larger first number and then counting up by the value of the second number (extending the fingers one at a time from the fist). 

To make this process even easier to understand (not here, but when teaching it in our worksheet) you could say - "What is 11 plus 4 fingers?"

Tell me the answer to the addition problems below.  I want you to get the answer to these problems in  the easiest and fastest way you know. 
Your student should use some type of "count-on" method and not be starting from 1 (as that would greatly extend the time it takes to get the answer). The answer really should be achieved in no more than 10 seconds, otherwise, the skill should be practiced.
