Brainstorming

Where do you find numbers?

Activity 1: Snakes and Ladders Note to teacher: 1. Divide class into two groups; Group A and Group B 2. One student from Group A is asked to roll the dice and read aloud the number obtained in English 3. The same student must then write the number obtained in words on the whiteboard. 4. One student from Group B is asked to roll the dice and say the number aloud and move the game piece accordingly. The student should then read the number on the square aloud and write the number on the whiteboard. 5. This procedure should then be repeated by a new student from each group.

Activity 2: Hundred number chart Fill the white cells with the appropriate numbers.

Numbers: Recap 0 – zero 1 – one 2 – two 3 – three 4 – four 5 – five 6 – six 7 – seven 8 – eight 9 – nine Numbers Note: Here, manipulatives can be used to allow students to relate the number to quantity.

Practice Match each of the numerals to its corresponding number name 1 nine 6 zero 4 one 9 four 2 six two

Connections between numbers Note: Numbers are connected to one another. Any number can be obtained by connecting two or more numbers together. For example, we can obtain “ten” through those number bonds shown below. Use your ten-frame to complete the rest.

Activity 3: Number bonds to 10 – Activities with 10 frames Note to Teacher: Make use of Ten Frame and bottle tops/ buttons as teaching aids.

Number bonds to 10 – Activities with 10 frames (Reys et al, 2009, p Provide opportunities for students to manipulate with the teaching aids (Bottle tops, buttons,…)

Activity 4 - Tens 10 ten 20 twenty 30 thirty 40 forty 50 fifty 60 sixty 70 seventy 80 eighty 90 ninety

Place value How are the following numbers different? 23 and 32?

Rs 23 versus Rs 32 Rs23 Rs32

Rs 23 versus Rs 32 23 = 20 + 3 32 = 30 + 2 = 2 tens + 3 ones (units) = (2 × 10) + ( 3 × 1) 32 = 30 + 2 = 3 tens + 2 ones (units) = (3 × 10) + ( 2 × 1)

Activity5 - Use of Ten Frames Rs 25 versus Rs 52 Give opportunity to students to manipulate the Ten Frame in exploring Place value.

Base ten blocks We can use Base ten blocks to represent numbers. unit ten hundred

Place value We can use money to understand hundreds, tens, and units

Activity 13: Number slider We can also represent numbers on a number slider for example: 346 (3x 100) + (4x10) + (6x1) Or in words three hundreds, four tens and six ones. To prepare 10 place value sliders Note: Each student is given a place value slider to input numbers

Place value: Expanded form In expanded form, we have 346 = (3 x 100) + (4 x10) + (6 x 1) = three hundreds + four tens + six ones. These are the expanded forms to write a number

Expanded form Qu 1. Using the Place Value slider, write the following numbers in expanded form a. 120 (…. x 100) + (…. x 10) + (…. x 1) b. 322 (…. x 100) + (…. x 10) + (…. x 1) Move parts c, d and e to next slide. c. 999 (…. x 100) + (…. x 10) + (…. x 1) d. 889 (…. x 100) + (…. x 10) + (…. x 1) e. 713
