For a basic addition problem direct your students to put three blue chips tens and six white chips ones together.
It is not wrong nor uncommon for kids at this age first grade to rely on counting on to get the answer ie. As you count hold up the base-ten rods so that at the end you will be holding 10 rods to equal 100. In the opening of the lesson I hold up one card from each stack to represent a two-digit number and have students use whiteboards and markers to draw tens and ones to represent the number.
Give each student their own place value mat 2 ten rods and 15 ones blocks. I give them 15 ones blocks so that if they have 9 ones and roll a 6 they can build the number before trading in 10. Every time he does it the way hes supposed to give him candy Etc.
Children see that 1 ten can be shown by filling a ten frame with 10 connecting cubes. When a student got to 100 he or she stopped and wrote 100 then started over and counted the remaining sticks. An activity to help children understand tens and ones.
For example 24 would have four individual sticks in the ones column and two bundles in the tens column. We can continue to group any tens that we have. There are 6 individual unit counters left over.
Addition and subtraction with number lines. We can begin by grouping the counters into tens. Call on students quickly and have them solve problems in which they add 10 every time 50 10 30 10 10 10.
Explain to him that when you add numbers that you need to add the smallest digit first so that your number isnt to small. Show on the board how adding 10 over and over is counting up and building bigger numbers. The extras then go to Mr Tens.

Add within 100 using place value blocks. One strategy that worked well for students was having them draw sticks that represent the amount of tens in each number then count and cross off each stick as they counted it. Add within 100 using a number line.
Try to make it fun so that he looks forward and listens. I hold up the number 35 students will draw 3 tens and 5 ones on their whiteboards. Show the students how one blue can be traded in for ten pink straws.
Again we should encourage kids to use numbers flexibly. Representing two-digit numbers in this way supports childrens understanding of the base-ten number system. Put a two-digit number on the board and have students visually represent the number by putting popsicle sticks into the place value columns.
This is the currently selected item. Teach addition with a carrying in stages over a period of time. Understanding place value when adding ones.
First make groups of ten then count the ten-groups and the individual beans separately. Addition within 20 without regroup Using the example of 12 3 a good way is to decompose the 12 into 10 and 2 then add the tens and ones separately. Give each pair one 6-sided die.
The pair will take turns rolling their die and putting that many ones blocks on their place value mat. Its 36 Keep riffing off of the. Any extra cubes outside the ten frame are ones.
So we write a 1 in the hundreds column. Count the blue straws and place them in groups of ten. All activities are easy to follow and can be used by teachers home schooling parents and students following distance learning.
Understanding place value when adding tens. Take 3 different colours say pink blue and yellow. Here we have found and circled 10 groups of ten which is the same as 1 group of one hundred.
When you introduce this form of calculation you must teach the learners to start with the units first. Tell the students the blue straws represent ones the pink tens and the yellow hundreds. Step 4 Keep the first number but add another and write the full sentence on the board eg.
