Give example of block model approach of solving mathematical word problem?
In the block model approach, mathematical word problems are represented using blocks or diagrams to help visualize the situation. For example, in a problem involving two groups of people, you could represent one group with blue blocks and the other group with red blocks. By visually representing the quantities and relationships in the problem using blocks, students can more easily understand and solve the problem step by step. This approach helps students develop their problem-solving skills and improve their understanding of mathematical concepts.
How can you represent values using variables?
You can represent values using variables. This can only be done with whole numbers.
Describe the range of numbers that can be represented by a 16 bit number using two complement?
A signed 16 bit number can represent the decimal numbers -32768 to 32767.
How many blocks per squ meter if they laid flat using 140 440 215 blocks?
Approx 14
Can you show 0.02 using only tenths place-value blocks?
No, it's impossible. If you did it with hundredths blocks then it would be fair.
What are the total number of ways to represent 127 using Base 10 blocks?
To represent the number 127 using Base 10 blocks, you can use a combination of thousands, hundreds, tens, and ones. Specifically, you would need 1 hundred block (100), 2 ten blocks (20), and 7 one blocks (7), which gives you a single unique way to represent 127 in this system. Therefore, there is only one total way to represent 127 using Base 10 blocks.
How do you represent the number 31219 in base ten blocks?
To represent the number 31,219 using base ten blocks, you would use 31 thousands blocks, 2 hundreds blocks, 1 ten block, and 9 unit blocks. This means you would arrange 31 large blocks for thousands, 2 medium blocks for hundreds, 1 small block for tens, and 9 individual unit blocks. This visual representation helps in understanding the place value of each digit in the number.
What is the least number of place-value blocks you need to show 4200 The greatest?
To represent the number 4200 using place-value blocks, you would need 4 thousands blocks (for the 4000), 2 hundreds blocks (for the 200), and no tens or ones blocks. Therefore, the least number of place-value blocks needed is 6. This includes 4 blocks for the thousands and 2 blocks for the hundreds.
How could you model 326 if you had no tens blocks?
To model the number 326 without using tens blocks, you can use individual units to represent the three hundreds as 3 groups of 100, and then represent the 26 by using 26 individual unit blocks. So, you would have 3 large representations for the hundreds and 26 smaller blocks for the ones, visually showing the composition of 326.
How do you draw 315 using exactly 36 blocks?
To draw the number 315 using exactly 36 blocks, you can represent each digit with a specific number of blocks. For example, you could use 3 blocks for the digit '3', 1 block for the digit '1', and 5 blocks for the digit '5'. This totals 3 + 1 + 5 = 9 blocks, but since you need to use 36 blocks, you can create a larger representation by stacking or arranging these digits in a way that visually fills the space with additional blocks while still clearly depicting the number 315.
What number can be shown using thousands blocks or only hundreds blocks?
2000
How many thousands blocks would you need to represent a million?
To represent a million using thousands blocks, you would need 1,000 blocks. This is because one thousand is equal to 1,000, and when you multiply that by 1,000, you get 1,000,000. Thus, 1,000 blocks of one thousand each equals one million.
How could you model 326 using exactly 20 blocks?
To model the number 326 using exactly 20 blocks, you could represent it as a combination of different block values. For example, you could use 3 blocks of 100 (representing 300), 2 blocks of 10 (representing 20), and 6 blocks of 1 (representing 6). This totals 20 blocks and accurately models 326 as 3(100) + 2(10) + 6(1) = 326.
How do you model 326 with only 20 base ten blocks?
To model the number 326 using base ten blocks, you would use 3 hundreds, 2 tens, and 6 unit blocks. This means you would take 3 hundred blocks (representing 300), 2 ten blocks (representing 20), and 6 unit blocks (representing 6) to visually represent the number 326. In total, you would use 3 + 2 + 6 = 11 blocks, which is within the limit of 20.
How many blocks are needed for for a three bedroom bungalow?
The number of blocks needed depends on whether you are using them for the walls or just the foundation, how high the walls are if you are using blocks forthem, the size of the blocks, and what the size of the bungalow will be.
How you can use base ten blocks to find 2.16 divided by 3?
To use base ten blocks for dividing 2.16 by 3, first represent 2.16 using the blocks: 2 whole units (two 1s) and 16 hundredths (sixteen 0.1s). Next, group the blocks into three equal parts to see how many blocks each group receives. Each group will get approximately 0.72, as you can represent this by distributing the blocks evenly. This visual method helps in understanding the division of decimals by breaking them down into manageable pieces.
How would you represent using z as the variable represent five less than twice a number?
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
