And the steady drumbeat of Ukrainian attacks on Russian ships is clear evidence that Ukrainian intelligence has no problem pinpointing the ships’ locations. president Joe Biden reportedly has signaled it will donate to Ukraine Army Tactical Missile System ballistic rockets that range as far as 190 miles.Įither prospective new weapon could hit Sevastopol from the Ukrainian side of the front line. Ukrainian industry is developing a new thousand-mile cruise missile and the administration of U.S. The number and variety of deep-strike weapons with which Ukrainian forces can attack the fleet steadily are growing. The Russian fleet’s security is going to get worse before it gets better. You will learn that whole numbers can be put together to compose a greater number. When Russian warships leave port, they do so briefly-usually only long enough to launch a few cruise missiles at Ukrainian cities. WHAT ARE COMPOSING & DECOMPOSING NUMBERS (1-10). Russian warships staging from Crimea are under constant assault as of last month, ships in Russia proper are at risk, too. Between its locally-made Neptune anti-ship missiles and Western-made Harpoon ASMs, as well as its missile-armed TB-2 drones and one-way drone boats, the Ukrainian navy isn’t just holding the Russian Black Sea Fleet at bay, it actively is beating back the fleet. The Ukrainian navy now effectively is a shipless navy, but no less dangerous for its lack of large hulls. The sinkings and raids are a remarkable feat for a Ukrainian fleet that, after scuttling its sole frigate in the early hours of the Russian invasion in February 2022, apparently has just one large ship left: an aging landing ship that has been hiding out near the mouth of the Dnipro River and occasionally lobbing short-range rockets at Russian forces. ![]() Decomposing numbers is the ability to break down numbers into their sub-parts. For example, kids will put together sets of objects, of smaller numbers, to make a complete set. Within the NCETM/Maths Hubs Mastering Number Programme, sessions are designed to build understanding of the composition of number for children in Reception, Year 1 and Year 2.ĭifferent patterns of spots are used, in different arrangements, and children are encouraged to ‘subitise’ (see without counting) the smaller numbers ‘within’ the bigger numbers.The Ukrainians also have sank or badly damaged several Russian patrol boats and landing craft-and also recently ejected Russian forces from a pair of captured Ukrainian oil platforms that the Russians had been using as naval outposts in the western Black Sea. Composing numbers is the ability to put two parts together to make a whole. ![]() When we add, we compose: when we subtract, we decompose. For those that understand composition of number, remembering that 2+3=5 and 5-2=3, and how these two facts relate, is less a matter of repetition and memorisation and more the application of structural understanding. Understanding composition also supports an understanding of commutativity: if you have learned that 2+3=5, then you also know that 3+2=5 without having to learn it as a new fact.Ĭomposition is also crucial in starting to understand addition and subtraction and their inverse relationship. So, back to the example of 5: number bonds of 5 are: 0 and 5, 1 and 4, 2 and 3. The concept of composition allows children to build fluency with number bonds – not only number bonds of 10, but all the number bonds within numbers. ![]() When 5 is partitioned into 3 and 2, then 3 is a part and 2 is a part and 5 is the whole.
