Once the children have learned to recognize the numbers from one to ten, they can begin to teach them the numbers from eleven to twenty. Understanding these numbers requires more than just counting and visual recognition; the child needs to become aware of units and tens and be able to learn a broader sense of how numbers work. Teaching these concepts can be difficult. For some ideas, go to step one.
Steps
Part 1 of 3: Introduce the numbers from eleven to twenty
Step 1. Show the numbers one at a time
Beginning with the number eleven, teach the children these numbers one at a time. Write the number on the board and add a picture - if you are teaching them the number eleven, draw eleven flowers, eleven cars, or eleven smiley faces.
It might be helpful to introduce the concept of ten, drawing a square with ten elements and marking the appropriate number of units in it. To find out more, go to the second part
Step 2. Teach the children to count to twenty
Children can usually learn to count to twenty quite easily by memorizing numbers. You can make it even easier for him by taking the numbers two at a time: First count up to twelve, then up to fourteen, and so on.
Note, however, that teaching children to count to twenty is not the same as teaching them to understand numerical values. Counting must be accompanied by other lessons aimed at giving them awareness and understanding of the number itself
Step 3. Practice them by writing the numbers
Once the children know the individual numbers and can count to twenty in the right order, have them practice writing the numbers. For best results, ask them to say them aloud when they are writing them.
Step 4. Create a number line
By showing children a number line, marked with numbers from zero to twenty, at regular intervals you will help them visualize the progression of the numbers.
Step 5. Use objects
Some children learn these numbers more easily when they can do it through objects they can touch with their hands. Have the children count sticks, pencils, cubes, marbles, or other small objects. Explain to them, several times if necessary, that if they count items one by one, the number they reach when they stop counting will be the same as the number of items they have accumulated.
Step 6. Make it physical
Have the children count their steps (stairs are great for this purpose but walking around a room works too) or ask them to do twenty hops, and then start over.
Playing hopscotch can serve this purpose. Draw ten squares on the ground and fill them with numbers from one to ten. Ask the children to count from one to ten when they advance and from eleven to twenty when they go backwards
Step 7. Have them repeat these numbers as often as possible
Take every opportunity to count to twenty and make the child aware of the numbers. The more they practice, the better the results.
Part 2 of 3: Teaching Units and Tens
Step 1. Explain the basic concept of tens and units
Tell the children that all numbers from eleven to nineteen are made up of a ten and a unit that adds to it. The number twenty is made up of two whole tens.
Help the children visualize this concept by writing the number eleven and showing a ten and a single unit next to it, separated by a circle
Step 2. Use a squared notebook
Draw a frame with ten empty squares that are to be filled in as you count. You can use coins or other small objects to fill the boxes, and you can even draw on the notebook itself.
The best method is to give each child two frames of ten and twenty objects of some kind. Have them create the number eleven: completely filling one frame and placing only one object in the other. Have them create the other numbers in a similar way. It is also possible to reverse the process, starting with frames that are already full and removing the objects one by one
Step 3. Try using dashes and dots
Show the children that these numbers can be represented using dashes and dots: dashes for tens and dots for units. Prove that the number fifteen, for example, consists of a hyphen and five dots.
Step 4. Divide a notebook page in two by drawing a T
The left column represents the tens; the right one, the units. Fill in the right column with the numbers from one to ten in the right sequence. Then:
- Add objects that represent the various numbers: a cube next to the number one, two cubes next to the two, and so on.
- Explain that one could represent a ten with either ten small cubes or a larger stick.
- Fill the tens column with sticks, one at a time, and explain how these numbers work together to create larger numbers.
Part 3 of 3: Review Numbers Eleven to Twenty with Fun Activities
Step 1. Create memory games with numbered cards
Use a set of cards marked with numbers from one to twenty to play a memory game. The children have to turn the cards face down and then try to find pairs.
Step 2. Fill containers with small items
Have the children fill containers with small items: eleven buttons, twelve grains of rice, thirteen pennies, and so on. Let them count the items and label the containers with the corresponding numbers.
Step 3. Read them picture books
There are many books available that deal with numbers from one to twenty. Read them together.
Step 4. Sing songs
Children's songs about numbers can help them learn while having fun.
Step 5. Play "Who has the number?
"Give the children cards marked with the numbers eleven to twenty. Ask a question," Who has the number fifteen? "And wait for the child who has the corresponding card to answer you.
You can make this game more challenging by asking harder questions: "Who has the number that is two more than thirteen?" Or you can ask your students to divide the number into tens and units after getting up
Step 6. Let the children correct you when you count wrong
Count aloud from one to twenty, deliberately making some mistake; let the children notice your mistakes. You can also do this while teaching them using number lines or a sequence of cards.
Step 7. Ask the children to use their hands
Choose two children. Assign one of them the role of "ten" - he or she should raise both hands in the air to show the ten fingers. The second child is "the unit" and should raise the appropriate number of fingers to create whatever number you require.
Step 8. Create seats in the classroom that represent each number
You should have a position for each number from eleven to twenty. For the number eleven, for example, label a desk with the written word "eleven," the number "11" and a photo of eleven items. Also, add 11 objects of any type. Do this for each number and tell the children to move around the class to find the various numbers.
Advice
- Do your best to make these lessons fun: Kids learn better from fun activities than they do from boring lessons.
- Remember that individual children have different ways of learning: some may do better if stimulated by visual images; others may need to touch objects. Try to use different methods to meet the needs of each pupil.
