The fun in learning is here! Our Kindergarten Math Series is one of the best kids math games your child can ever play. Introducing Mari’s Kitchen! The second app in iO School’s Kindergarten Math Series! Aimed to provide an enjoyable learning experience, the six kindergarten math apps are designed to match your child's lessons for the entire school year. It’s a complete kindergarten Math Curriculum for your 5 year old. Whether it’s to practice or hone your child’s math skills, the Kindergarten Math Series is a perfect program to supplement your child’s learning at school and at home. The schedule below shows the time frame for playing the Kindergarten Math Series: Saba’s Island (Saba the monkey) - Month 1 to 2 Mari’s Kitchen (Mari the bear) - Month 2 to 4 Pat’s Voyage (Pat the parrot) - Month 4 to 5 Joe’s Jungle (Joe the squirrel) - Month 6 to 7 Pearl’s Pizza (Pearl the cat) - Month 8 to 9 Clifton’s Cruise (Clifton the dog) - Month 9 to 10 Playing each app ahead of schedule is entirely up to the parents. They can also go back a month or two to review the skills that they have previously learned at school. Parents who have preschool age children (4 years old) can introduce their child to the Kindergarten Math curriculum by playing the Kindergarten Math Series. Skills Covered in Mari’s Kitchen: Rote counting to 80 Writing numbers 11 to 20 Count objects in an array 0 to 20 Counting objects on two 10-frames Ordering number symbols 0 to 10 Ordering objects from least to greatest 1 to 10 Ordering objects from greatest to least 10 to 1 Comparing objects with smaller or larger and greater or fewer Ordering numbers symbols from least to greatest and from greatest to least (0-20) Comparing objects from smallest to largest and fewest to greatest Counting objects in a random array 11 to 20 Comparing objects greater than, less than and equal to Comparing numbers greater than, less than and equal to Graphing objects in an array Ordering numbers starting from anything but the number 1 Whether it's counting vegetables, pots and pans or writing numbers, Mari needs to complete the task from each NPC (non-playable character) to be able to move to the next level. Each level starts with skills practices in every mini game and lets players earn ions that they can use to buy different kinds of gear from the shop. At the end of each level, they will complete challenge activities that get recorded on the Parent Dashboard. Track your child’s progress using the Parent Dashboard Parents can create a free account at https://app.ioschool.com or on the app itself. They will be able to see what skills their child worked on and how they did on the assessments. Each session is recorded by the date. Parents can determine if their child is progressing or will need additional support and practice.

Chemical Elements Quiz & Study

Put your knowledge of the periodic table to the test with this entertaining chemical elements quiz app! Unlike other apps where you're presented with options where you can make mere guesses, this app demands that you type the name of the chemical element of the periodic table! Study the elements then take the quiz. How to play: 1. Start by typing the element's name. Once you're done, dismiss the keyboard by clicking return or by tapping any part of the screen. Next, click the "Show Answer" button to reveal the name of the chemical element to verify your answer. If your input matches the chemical element's name, you win, otherwise no! 2. Click the "Next Element" button to go to the next element. 3. Turn on "Randomize" switch to get the chemical elements randomly. In 1789, French chemist Antoine Lavoisier tried grouping the elements as metals and nonmetals. Forty years later, German physicist Johann Wolfang Döbereiner observed similarities in physical and chemical properties of certain elements. He arranged them in groups of three in increasing order of atomic weight and called them triads, observing that some properties of the middle element, such as atomic weight and density, approximated the average value of these properties in the other two in each triad. A breakthrough came with the publication of a revised list of elements and their atomic masses at the first international conference of chemistry in Karlsruhe, Germany, in 1860. They concluded that hydrogen would be assigned the atomic weight of 1 and the atomic weight of other elements would be decided by comparison with hydrogen. For example, carbon, being 12 times heavier than hydrogen, would have an atomic weight of 12. British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. He arranged the elements in eight groups but left no gaps for undiscovered elements. In 1869, Russian chemist Dmitri Mendeleev created the framework that became the modern periodic table, leaving gaps for elements that were yet to be discovered. While arranging the elements according to their atomic weight, if he found that they did not fit into the group he would rearrange them. Mendeleev predicted the properties of some undiscovered elements and gave them names such as "eka-aluminium" for an element with properties similar to aluminium. Later eka-aluminium was discovered as gallium. Some discrepancies remained; the position of certain elements, such as iodine and tellurium, could not be explained. German chemist Lothar Meyer produced a version of the periodic table similar to Mendeleev’s in 1870. He left gaps for undiscovered elements but never predicted their properties. The Royal Society of London awarded the Davy Medal in 1882 to both Mendeleev and Meyer. The later discovery of elements predicted by Mendeleev, including gallium (1875), scandium (1879) and germanium (1886), verified his predictions and his periodic table won universal recognition. In 1955 the 101st element was named mendelevium in his honor. The concept of sub-atomic particles did not exist in the 19th century. In 1913, English physicist Henry Moseley used X-rays to measure the wavelengths of elements and correlated these measurements to their atomic numbers. He then rearranged the elements in the periodic table on the basis of atomic numbers. This helped explain disparities in earlier versions that had used atomic masses. In the periodic table, the horizontal rows are called periods, with metals in the extreme left and nonmetals on the right. The vertical columns, called groups, consist of elements with similar chemical properties. Scientists use the table to study chemicals and design experiments. It is used to develop chemicals used in the pharmaceutical and cosmetics industries and batteries used in technological devices.
